How Do I Know If My Dog Is Overweight?

Before considering the best weight management dog food, you should determine if your dog needs to go on a diet. Every breed and dog size has a narrow ideal weight range, and your veterinarian can help you determine if your dog is at a healthy weight. But there are a few quick signs that you can look for at home.

  • Can you easily feel your dog’s ribs without having to press down? If not, he very likely needs to lose weight.
  • Look at your dog from above; if your dog looks oval-shaped, your dog is likely overweight. If your pup has an hourglass shape, he’s probably at a healthy weight.
  • Have a dog with a defined waist and a straight body down the sides (i.e., no love handles)? Then his current weight is probably okay.

Best Dog Food For Weight Loss

Always consult your veterinarian before putting your dog on a weight loss diet. Your dog’s weight gain could be due to an underlying condition, so it’s important to rule out any potential problems. Your vet can also help you make sure any diet food you’re considering will give your pup all the nutrients he needs. With that said, here are our top picks for weight loss dog food options.

Our First-Hand Experience

Lexie before and after Farmer's Dog

We switched our dog, Lexie, from kibble to The Farmer’s Dog shortly after rescuing her. Because King Charles Cavalier Spaniels are prone to heart conditions (which are onset by obesity), we wanted to make sure she maintained a healthy weight.

She not only shed a few extra pounds, but we also noticed an improvement in her coat’s shine and her energy level. She’s been a fan ever since and gobbles it down!

Over time, I started mixing it with a little rice (or kibble) to stretch the packs out and add grains to her diet, and she didn’t gain back the weight (which is shocking because Lexie is not very active). The before and after photos were taken one year apart after switching from kibble to The Farmer’s Dog. – Sadie C., Canine Journal
