The best weight loss food for your pup is the one that fits their individual needs

There are so many options for foods that can help your pooch lose weight, so it can be challenging to choose the one that’s right for them. But, the best weight loss diet for your pup is one that fits their individual needs - because every dog is unique and can have different nutritional requirements.

There are a lot of factors to consider when choosing the right diet food for your dog

With so many diets, with different nutrition labels and health claims on the market, it's easy to feel overwhelmed picking the best food for your overweight dog.

Thankfully, with a little bit of help from our vet, we can make that journey a bit easier for both you and your furry friend.

Trying to get some weight off your portly pooch is a great idea, and it can really benefit their health but how do you choose one that works for your dog?


Firstly, make sure to get the right food for the age of your dog, as there are often different types of foods available for senior and younger or middle-aged doggos. These foods are nutritionally slightly different, so your dog gets exactly what they need. Some brands even go as far as doing breed specific foods as well as age ranges.


It’s also important to think about any allergies or intolerances your dog might have to an ingredient. For example, some dogs can get itchy skin with some foods, and others might get an upset stomach. In those cases check ingredient lists to make sure what doesn’t agree with your pup isn’t in there.


Also make sure it’s a flavour your dog likes. If your dog says no thanks to anything fishy, maybe stick to the meat option. And if your dog only eats wet or dry, be sure to go for the option that they will eat.


Is your dog neutered? Or do they need to be on a special diet for health issues? If the answer to either of these are yes, this can affect your choice of food as well.


Is it the right price? We all love our dogs hugely, but that doesn’t mean there is anything wrong with cost-effective dog food that can help your pooch lose weight without a big price tag. So check what the cost of the food will be longer term, after any introductory offers or sales have finished, and see if it will be something you will be able to buy again.


You want to make sure you can get the food easily too. Whether you go for a subscription, buy online or in-store, make sure the food you go for is something you can settle your dog on for a good length of time.

Remember to always consult with your vet before making any changes to your dog's diet

Our four-legged friends rely on us for all sorts of things, from going on walks and providing belly rubs, to supplying the proper nutrition for their well-being. But no matter how much we think we know about our doggy's dietary needs, it is always best practice to consult with a vet before making any adjustments.

If you want to try a new dog food, be sure it suits your individual dog, and gradually change your dog over from their old food. And if you’re trying to shed some pounds off your pooch, make sure to weigh the amount of food their getting, and cut out those treats and leftovers.

Now that you know everything there is to know about finding the best diet food for your pup, it's time to get their dinner ready!
