How skinny is too skinny for Golden Retrievers? 

If your Golden Retriever’s typical adult weight fits within the breed standard for weight and is constant, it is at a healthy weight and not considered skinny. Female Golden Retrievers should weigh between 55 and 65 pounds, while males should weigh between 65 and 75 pounds.

So if your adult golden retriever’s weight is a lot less than the weights mentioned above, your dog is probably too skinny.

When your Golden Retriever’s weight loss reaches 10% of his or her usual body weight, he or she is considered underweight. The ribs, hips, shoulders, and backbone may be apparent and easily felt as physical symptoms. Furthermore, the abdominal taper between the ribs and hips may be severe, with little to no body fat.

Bear in mind that each dog has its individual characteristics and body type which gets affected by multiple aspects, so as long as your dog is closer to this range, it is fine, but if you notice a huge difference, this should get your attention.

7 Possible Causes Your Golden Retriever is Too Skinny (and their solutions) 

Golden Retrievers, similar to us humans, may get skinny for various reasons, mainly 7:

Malnutrition/ Improper diet

Your golden retriever may be losing weight and becoming skinny-looking because either he’s not getting enough food or getting food that is of low quality – both are inadequate for his daily nutritional needs and optimum health, which results in weight loss.

Solution: Ensure the diet you choose is complete and balanced. It’s best for your vet to write you down everything your dog should and shouldn’t be eating; but as a rule of thumb: You can feed your dog poultry, meat (cooked or raw), and vegetables for variety.

Choose large, raw, meaty bones. For recipes and recommendations, check out my guide to Golden Retrievers foods and treats for every age here (I even included homemade Ice cream, so make sure to check it out).

Your dog could also be eating the wrong diet for their age. For example; they’re still eating puppy growl when they should be on an adult diet by now. You can learn when and how to switch your golden to adult food here.

Health Issues

An underweight Golden Retriever or one that is losing weight too rapidly may be suffering from parasites, diabetes, or thyroid problems. This is especially probable if he has suddenly grown thin and has been exhibiting other symptoms of illness such as tiredness, a lack of desire to eat, or vomiting.

Solution: If your dog appears to be unwell or has a medical issue, the best course of action is to take him to a veterinarian.


It’s possible that your Golden Retriever’s thin look is hereditary. This is more likely if his parents were skinny by nature or if he was reasonably skinny as a puppy if he did not become skinny abruptly, 

Solution: Pay your vet a visit, and If you have been feeding it the proper quantity and the vet detects no problems, then it goes back to genetics.

It would not be a reason for concern in this situation unless your dog has been exhibiting symptoms of health issues.


Have you recently started leaving your golden retriever alone for long periods of time? Have you gotten more busy than usual? Have you gotten a new puppy? These can all cause your dog to feel stressed which may cause a lack of appetite and weight loss 

Solution: take a look at any changes that may have happened recently that could be causing stress to your golden retriever and try to get him used to this new environment.

Being a picky eater

If your dog is a picky eater, it may be difficult to convince them to eat enough to be healthy, as he will be repelling away from the food he doesn’t like – eating based on taste, not nutritional needs and hunger. 

Solution: If you feed your dog dry food, you may want to try topping it with wet or fresh food, and try encouraging your dog to eat whatever there is by not changing food if he refuses to eat.

Exercising routine

Golden Retrievers normally need a minimum of 1 hour of high-intensity exercise every day to keep them healthy and free of any pent-up energy that may cause them to act aggressively or have a change of behavior.

But if your dog is getting too much exercise and not enough nutrients to compensate, then he may lose weight excessively. 

Solution: the key is balancing between the energy that your dog spends and the intake of food that meets his nutritional needs.

Change of Environment

Did you move to a new house recently? Did you change parks? Has the staying or sleeping area of your dog changed? Changes in the dog’s surroundings or daily routine may cause a bit of confusion and anxiety thus lead to weight loss 

Solution: make sure your golden retriever isn’t having a hard time adapting as it may lead to their loss of appetite and them becoming more skinny than they should be.

How to fatten up your golden retriever 

There are always methods you can use to make your golden retriever gain a little bit of weight, but make sure you choose the right, healthy track.

Here are some tips that will help you fatten up your golden retriever:

  • Feed your dog high-protein food
  • Make sure the amount of exercise matches the amount of food he gets and not exceed it by a mile.
  • The focus of high-fat dog food — either dry, canned, frozen, and/or freeze-dried 
  • Feeding your dog high caloric food and treats
  • Supplement meals with snacks 
  • Give your dog three meals a day instead of one meal.

Why is your golden retriever not gaining weight even though they’re eating?  

Your Golden Retriever may not be gaining weight even though they’re eating because he may need to eat more food, stressed, or he may have a health problem that requires care. If this does not improve, it is advisable to get him examined by a vet to inspect him and determine what is causing this.

When to worry and check the vet? 

If your dog wasn’t always skinny or one of his parents at least was, or if you notice that your dog is eating quite a lot yet not gaining any weight then you should look into the matter as it may be caused by an underlying health issue.

Physical signs that should catch your eye include: 

  • You can see your dog’s Ribs and backbones from afar.
  • It’s visible that your dog has very little or no body fat.
  • You can see and feel your dog’s ribs.
  • The slope from waist to hips is exaggerated and noticeable.

These signs are often your red flag to go and see the vet.
