As dog lovers, we want to do everything possible to provide our pups with the best life ever. And sometimes, that means spoiling our dogs with all sorts of treats, chews, and table scraps.

I don’t think there’s anything wrong with that. However, I do believe that moderation is key.

I’ve gone to far too many consults where I’ve noticed a dog I’m working with is carrying way more weight than he should be.

While some people think it’s cute to have a pudgy pup, excess fat can have detrimental effects on a dog’s health and well-being.

So, how dangerous is it?

Keep reading to find out more about YOUR dog’s weight and health…

Canine Obesity: Is My Dog’s Weight Damaging His Health?

Our dogs may look adorable when they’re on the heavy side. But, dogs who are obese are far more likely to develop serious health problems than those who are lean.

According to the Association for Pet Obesity Prevention, the number of overweight dogs is increasing at an alarming rate each year.

In fact, in 2017, 56% of dogs were classified as obese!

That’s essentially one in every two dogs.

What’s worse is most dog lovers don’t realize how the excess weight is affecting their furry best friend so they don’t try to help their dog lose weight.

Often dog owners also don’t realize that their dog has gained the weight—especially when the weight gain is very gradual.

This is why it’s so important to keep a close eye on your dog. Catching a dog’s weight gain early will significantly help you get it back under control in order to prevent dangerous diseases and other health issues.

How to Tell If Your Dog Is Overweight

Chances are, if you’re reading this right now, you are worried about your dog’s weight.

The good news is that you're in the right place! And, I’m going to share some steps you can take to determine if your dog is dangerously obese or not.

If you’re not sure if your dog is overweight, the first step is to bring your dog to the veterinarian to step on the doggy scale.

Your vet will review her charts and check to see if the weight gain is alarmingly higher than your dog’s last visit.

Your veterinarian can also let you know if your dog is overweight based on the “body condition scale”.

The body condition scale is a hands-on technique that helps measure the health of your dog.

If you can’t take a trip to the vet, you can try the “rib check” at home.

Click here to get step-by-step instructions on how to do the rib check!

On a healthy dog, you’re able to feel the ribs under a thin layer of skin. If you need to push into your dog to feel her ribs, there’s a good chance she’s overweight.

After you have felt for your dog’s ribs, it’s important to get a side view.

Is your dog’s belly sagging toward the floor? If so, this is another sign your dog may be overweight. Dogs with a healthy weight generally have a taper to their stomach.

The last way you can check is by standing over your dog. Your dog should have a silhouette like an hourglass. If your dog appears to be rounded from the overhead view, he may be overweight.

Should an Overweight Dog Be Put on a Diet?

If or when you do notice your dog is overweight, you should not immediately place your dog on a diet.

The reason: Weight gain often indicates that your dog may have an underlying medical condition.

If you notice your dog is gaining weight, it’s best to take him to a veterinarian who can run blood tests to check for abnormalities.

Conditions like hypothyroidism and Cushing’s disease could be the reason your dog is obese, and a diet alone won’t fix the weight gain.

If your dog does check out normal at the vet, then it’s a good time to put your dog on a diet.

Be sure to ask your vet how much your dog should be eating and what types of food he should be given to lose the excess pounds.

Dog Diets: How Much Should My Dog Eat?

If you have the medical clearance from your veterinarian, you may want to immediately place your dog on a diet.

That being said, a dog’s diet isn’t a “one-size-fits-all” solution.

Every dog is different and requires a different amount of food.

One of the most common reasons dogs become overweight is that they have been fed based on what the label on the dog food says. It’s important to understand, the label is a general guideline—it’s not correct for every dog.

To determine exactly what portion of food your dog should eat, a number of factors need to be considered including your dog’s…

  • Weight.
  • Activity level.
  • Breed.
  • Gender.
  • And more!

As I said earlier, your veterinarian or canine nutritionist can assist you in putting together a meal plan that will work for your dog.

What Will Happen If I Don’t Help My Dog Lose Weight?

Dogs who are obese are at greater risk for developing:

For these reasons, dog obesity is a serious problem and not to be taken lightly.

If your dog is overweight, now is the time to start putting measures in place to help him lose a few pounds to avoid these horrible health issues.

The Bottom Line on Dog Obesity

Obesity kills dogs every day and is a matter that should not be taken lightly.

If your dog is obese, it’s important to place him on a strategic diet and exercise routine. For more information check out this article.

Most important, it’s vital that you follow through with the weight loss routine in order to prevent your dog from becoming obese again.

Follow your veterinarian’s instructions, and it won’t take long for your dog to get back to living a happy, comfortable, and healthy life.

While we’re on the topic of food, I wanted to quickly mention treat training.

Food can be an incredible motivator, but it can also negatively impact your dog's health and ability to listen to you when it matters most.

For that reason, I’ve decided to put together a FREE guide for you on the ➜ Dos and Don'ts of Dog Treat Training (including 5 of the more popular treats your dog will love!)

  1. We have a 8 month old part Poodle part Shihzu. Problem separation anxiety. Even pees on his crate when we leave. Any suggestions?

    1. Hi Becky, I have posted a previous Blog about Separation Anxiety which you may be interested in looking at. It’s a very common behavioural issue and my website TheOnlineDogTrainer.com shows you very clearly how to overcome this behaviour…maybe take a quick look…its a $1 trial for 3 days…all the best Doggy Dan

  2. The health risk to overweight dogs is serious. A gain of even a pound or two of additional fat on some dogs and cats can place significant stress on the body. Some of the conditions that can occur as a result of excess weight are: Exercise intolerance, decreased stamina.

    1. I absolutely agree John! The easiest thing to change to help dogs slim down is to feed them less. I do acknowledge that this can be emotionally hard for many owners but it really is far better for a dog than masses of exercise. It’s all about energy balance, with us as well as dogs! Best, Doggy Dan

  3. I have a Deer Head Chihuahua 11 years old and the Vet recommend diet, he said she was 3# over and he said to give 4 ounce of food a day. She loss 1#1/2 in no time. But she was starving at supper time,I start give a bit of food and she is gaining weight again.What should I do?Thanks

    1. Hi Nancy,
      Moderating food is the best way to help a dog lose weight but I find that if you cut their food intake too significantly then they do tend to notice it a lot more. So a more gradual approach may work for your dog. You can also add volume to a dog’s food by adding low calorie food like broccoli and other appropriate greens such as spinach and kale. Splitting your dogs meal into two or three feeding sessions may also help. Best Doggy Dan

So far, so good! We started the Calming Dog a few weeks ago and while we humans have not been perfect at it, we are seeing differences in our dog. He is an incredibly reactive and protective dog, so the changes we have had to date are a huge blessing. I'm impressed at the approach, the actual simplicity of it combined with the science of dog behavior. Thank you, Doggy Dan and team!

Ridley is my 4th dog. After listening to and learning from Doggy Dan, I was happy to see that I did pretty well with my first 3 dogs while raising my kids and having my husband with me. Not perfect - but pretty good! Now I am raising a new dog by myself, and I feel like I'm not doing this really "alone." I really am so happy with all the information Dan has offered... and all his techniques work well!!

Two months ago I adopted a 7 year old Morkie, a very nervous but loving little fellow. I tried several different training techniques and even purchased a program that was lengthy and very time consuming before I discovered Doggy Dan. I've been using his program for two weeks and am astounded by the change in my Dexter. He is calmer, more obedient and friendlier to others than I imagined possible. Dan's training is concise. It differs from others I found, Dan trains you to become the leader of your pack through a dog's perspective. I like that the training is specific yet compassionate. This is a program that works if you are consistent. Thanks Doggy Dan!

Susie in the UK. I am only 10 days in but took in a 9 yr old emergency rescue from Romania who had been in kennels for 6 years and then had 3 failed foster placements in the UK. Luca is a big powerful mixed breed with huge stress and anxiety and very reactive, he bounded into my home and took over - aggressive with my 2 others, and visitors and pulling and pushing on walks. I thought I couldn't handle him but saw an advert for Doggy Dan on line and signed up - we've had a wonderful turnaround and he is finally decompressing, being polite with my dogs and responds excellently to the time-out if reactive with guests. Walks are much better and all 5 rules are in place. I believe he will continue to improve but only if I remain 100% consistent with him for the rest of his life. He is 9 years old and deserves a happy old age being loved and looked after with no further upsets in his life so fingers and toes are crossed for him

I started. The course 3/4 weeks ago. As Dan says you have to work on things if you get stuck. I have a Staffordshire x cane corso who is now six months old. She is very intelligent but sometimes she just doesn’t listen. Doing the five codes I’m finding it’s going pretty well except trying to get her calm so I am persevering with it again with my own space. I have a trainer call shortly which I will ask for advice on this. It’s great also that you can ask anything you’re not sure of on line. It’s so great to have someone there to help. I’m looking forward to having a relaxed girl instead of hyper most of the time as she gets so excited about almost everything. I would truly recommend doggy Dan and just wished I would have come across him much earlier. Thanks again for everything so far.

This program is amazing!. We have a VERY reactive rescue dog that has bitten his previous owner and as well, myself 3x and my husband 4 x's. He had never been around people or other animals, and had never been walked on a leash. (in fact never run off-leash either, just tied to the front steps). We began with traditional treat-based training with a professional, but the progress was frustrating. A reactive dog does not want treats; it wants comfort. With the 5 Golden Rules and and some of the other training we have received with our subscription, in just 3 weeks, we can let him off leash at the dog park, he has not growled at any stranger, and he has not attacked any other animals. He is still a work in progress, but we see progress!!!! He has become a cuddly, sweet dog and for a greyhound, he even has recall! This program is amazing to say the least. We were at our wits end, but now we have hope.

Okay, he says it’s not magic, but the results and the peace in so little time with so little effort sure feels like magic! My 11 month old pup was a 60lb highly reactive, very loud disaster waiting to happen. Now we are both calm, the house is quiet and I don’t live in absolute fear of his reactivity towards others. There’s always still work/training to do of course, but wow are we in a much better place to get on with that!

Just started with the 5 rules. It's only been a week and a half and I'm noticing less stress, and a reduction in reactivity. We still have a way to go. But finally something I can work with. I went for the online course.

We have an 8 month old Goldendoodle who has fear issues outside the home and gets easily overwhelmed going into panic/flee mode if several triggers coincide (people, loud dog barking and noises like motorcycles/construction). So pleased to find Doggy Dan and seeing positive changes after just two weeks. Feeding time is calm after using the gesture eating and "thank you" when he barks works a treat. I realized I'm babying my dog too much and trying to be his best pal instead of a leader so I'm working hard on that. We've changed to the no pull harness and love that. Doggy Dans video clips really help bring the philosophy together and I love his attitude. He is calm, clear, firm but so kind and loving with dogs and very down to earth and relatable. I've got great help too from the AI coach and the daily emails and videos help keep us on track and feeling positive. We've still got a mountain to climb with our pup but I finally feel hopeful and supported. We'd tried trainers, behavior specialists and all sorts before finding Doggy Dan and this is by far our best investment. Can't recommend you trying this highly enough. Photo of our boy.

I couldn’t believe my dog’s problem resolved completely within a week! Easy but not easy if you are inconsistent with the 5 rules. I highly recommend this method! Somethings don’t seem important or relevant but they are!

I just started my training about 2 weeks ago, and I do mean MY training. My 2 girls are really responding to my changes in how I am relating to them better. Thank you Doggy Dan, I really needed this win, 2 reactive dogs and we have made progress with the 5 golden rules and we have not with anything else.

For three years, I tried every treat-based method and expensive course to stop my large, powerful male dog from pulling on the leash, barking, and stressing out when his energy got too high on our walks. (So while he is a farm dog who enjoys total freedom off-leash on our farm most of the day, on-leash in the city, he totally lost it). He was practically hanging from the leash, two feet in the air (almost strangling himself), always demanding to walk in front and make all the decisions. Absolutely nothing worked—until I found Doggy Dan! 🏆 After just a couple of weeks implementing The 5 Golden Rules, the transformation is absolutely mind-blowing!!! By focusing on connection and calm leadership rather than rigid commands, my dog has FINALLY reconnected with his natural calmness (that has actually always been there inside him) ❤️❤️ When we walk through town now, I look down at my dog walking in a perfect "heel." The leash hangs completely loose, and that loose leash really says it all 👍👍👍 He does not pull, bark, or growl AT ALL when other dogs bark at him!😱 Yes, he looks at them and is interested, but he remains completely calm. We pass shouting people, groups of kids on scooters, and dogs barking aggressively behind gates—he is interested, but he remains entirely unfazed. Just yesterday, we stopped in front of a fence with chickens walking in a garden, and he just stood there watching curiously, staying completely still. And as we walked across a large, grassy schoolyard, we suddenly crossed paths with two rabbits—when I told him to, he immediately sat down. Of course, he was highly interested, but he sat completely, utterly still! I constantly find myself thinking: This can NOT be my dog, LOL! 🐇🐓 Dan refers to himself as a dog trainer, but in my humble opinion he is a dog philosopher. The course is incredibly generous, filled with hundreds of real-life videos from every situation imaginable, offering a massive toolkit for an amazing price. I am so excited to continue this course, so happy about the progress, and so looking forward to the future with this beloved dog of mine. I HIGHLY recommend it! ⭐⭐⭐⭐⭐

I've only been working the program for a week and already are seeing some great improvements with an overexcitable, energetic, barking at everything, and fun Maltipoo. I'm focusing on the 5 golden rules and watching the training videos. Thanks Doggy Dan!

In a matter of days my 5 year old Frenchie is calmer and seems happier, albeit not happy that I'm ignoring him but it works! I live alone so he thinks he should be boss and protect me from every visitor but he didn't even bark at the window cleaner yesterday, just followed him around each window. My life might be my own soon, thank you!
