Key Things to Look for

Picking the perfect food to help your dog lose a few pounds isn’t an easy task, but these key features you should be keeping an eye out for will certainly lighten the load a little.

Age. This is actually a vital part of weight loss for chunky pups. This is because puppy food has much higher calories and fat content than adult food, which can cause weight gain and pancreas issues when fed to adult or senior dogs for prolonged periods of time.

Calories. You should check how many calories each food has before you serve it, that way you can make any necessary adjustments to the quantities being served. You’ll find this number on the packaging, but you can also rest assured that our chosen foods are low calorie.

Ingredients. Weight loss foods should be low in fat, of course, but you also want to watch out for filler ingredients. These provide little to no nutritional value while making your dog feel fuller after each meal.

These ingredients include potatoes, cereals, wheat, and grains. While they are often fine in small quantities, you want to watch out for weight loss foods that use these in excess, sometimes even dwarfing the protein content in comparison.

Protein Content. One of the main issues you will find with weight loss foods is that they contain very little protein when compared to standard ones. This means your dog isn’t getting as many good nutrients, and it can be difficult to separate the good protein foods from the bad ones.

Vegetable Content. While you don’t want too many vegetables in your dog’s food so that they still get a good amount of protein, some vegetables are important. They are nutritious and packed with important minerals, but they also bulk up the food in a positive way to help them lose weight as well as maintain it.

FAQs

How Much Weight Loss Food Should I Feed My Dog?


The amount of weight loss food that you feed your dog will vary according to how much weight you want them to lose as well as their size.

You will find a feeding guide on the back of the packet, and it is best to start by following this and then adjust it as needed for your pup once you have a good understanding of how much they need each day.

What is the Safest Rate of Weight Loss for Dogs?


The safest rate of weight loss for dogs is 1-2% of their body weight each week. This is because rapid weight loss can cause serious health issues and may also cause weight to be put back on faster when they get little extra treats or you increase their food quantity.

How Do I Know if My Dog Has a Sensitive Stomach?


If your dog has a sensitive stomach you will normally notice things like diarrhoea, bloating, and excessive wind. In some cases, there might be blood in their stool or vomiting. Nausea is also a common symptom, and if your dog is licking their lips a lot this usually means they feel unwell.

What Causes Dogs To Have a Sensitive Stomach?


Generally speaking, sensitive stomachs are caused by intolerances or sensitivities to certain foods and ingredients. This can include common intolerances such as wheat and grains, each of which is often the cause of bloating, gas, and nausea.

Is Wet Dog Food Better for Weight Loss?


Yes, wet dog food can be better for weight loss. This is because they are often lower in calories and fat but higher in nutrients and protein. They usually have fewer carbs than dry food as well, which means fewer filler ingredients.

How Do I Determine My Dog’s Ideal Weight?


Determining the ideal weight for your dog can be a little tricky, namely because there are multiple factors. One of these is the breed of dog that you own, as they will have a weight spectrum that they should be on in order to be healthy.

However, the ideal weight is also based on visuals. The waist should be tucked behind the ribs, but not so much so that you can visibly see the outline of the ribcage. If the waist is in line with the ribs or bulges past it, then your dog is likely overweight.

Final Thoughts

If you are ready to go on a journey of weight loss and good health with your dog, choosing the right food to get the job done is key. It’s important to tackle weight issues as early as possible to avoid them becoming obese or suffering from crippling illnesses related to them afterwards.

The foods that we have chosen to be used in this guide reflect the importance of choosing a weight-loss food that is good quality, while also being aware of the fact that everyone has different budgets that need to be catered to.

Every food here is exceptional, but we would absolutely recommend Barking Heads and Royal Canin for your dog.
