Snacksfor dogs and cats are much more than just a tasty treat. They play a key role in training, rewarding good behaviour and keeping pets mentally engaged. Still, responsible snacking is essential to ensure your pet’s wellbeing. In this article, vet Lobke explains what to look out for when giving treats, how to spot warning signs, and how to pick the perfect snacks for every life stage.

Snacks as part of daily life

Snacks are not only a great way to positively reward your pet during training, but also an excellent way to strengthen the bond between you and your pet. A well-chosen snack can also provide mental stimulation: chewing, licking or puzzling with snacks keeps your four-legged friend occupied and prevents boredom.

Just remember: treats should never replace a complete meal. They’re a nice extra, not the main course. Vet Lobke advises that snacks should make up no more than 10% of your pet’s daily calorie intake. This means that most of your pet’s daily calories should always come from a complete and balanced diet, tailored to their age, weight and overall health.

Giving your pet too many treats, for example, can lead to overweight, a problem that is becoming increasingly common in both dogs and cats. Being overweight increases the risk of health problems such as joint pain, cardiovascular disease, diabetes, or reduced quality of life. On top of that, snacks that are too fatty, salty or heavily processed can cause digestive or dental issues.

How to recognise health problems caused by snacking?

Dogs and cats often show subtle signals when they don't like a snack or when health issues start to develop. It's important to be alert to these signs so that you can make adjustments in time.

Overweight in dogs and cats

Weight gain is one of the most common health issues in pets – and it can seriously impact their wellbeing. Watch out for the following signs in your four-legged friend:

  • Reduced waistline: your dog or cat no longer has a clearly defined, slim shape.
  • Heavy panting or getting tired quickly:your animal becomes short of breath more quickly during exercise.
  • Less interest in playing or walking: a clear reduction in activity may indicate extra weight.


In cats, obesity is a particularly high risk. Many cats are indoor pets and no longer need to hunt, which means they exercise less. That's why it's crucial to offer snacks in small portions and avoid high-calorie extras such as dairy products or biscuits. Choose light, tasty snacks that support weight control instead.


Dental problems caused by snacking

Not every treat is good for the teeth. A snack that’s too soft or sticky can contribute to plaque and tartar build-up. Watch out for the following signs in your pet:

  • Bad breath
  • Tartar build-up or discolouration
  • Excessive drooling or difficulty chewing
  • Chewing on one side only or taking food carefully


By choosing dental-friendly snacks or chewing products, you help maintain good oral health and prevent painful dental problems.


Digestive issues caused by snacks

Some snacks can put a strain on your pet's digestion, especially if they are too fatty, too salty or difficult to digest. You can recognise this by the following signs:

  • Vomiting
  • Diarrhoea
  • Flatulence
  • Irregular stools


For sensitive pets or young puppies and kittens, it’s especially important to offer light, easily digestible snacks. This reduces the risk of discomfort and keeps snack time enjoyable for your pet.

Snacks tailored to every pet: puppy, senior or sensitive four-legged friend

Not every pet benefits from the same snack. Age, health and sensitivities play an important role in determining which snacks are most suitable. By matching the choice of snacks to your pet’s life stage, you ensure that your loyal companion benefits from the extra treats without any health risks.

For young pets, light and easily digestible snacks are the most suitable. These snacks support growth and are gentle on the stomach and intestines.

Older dogs and cats often have more sensitive teeth and may have difficulty chewing. Soft, tooth-friendly snacks are ideal for senior pets, as they are easier to chew and contribute to oral health.

Pets with food intolerances or sensitive digestion benefit from hypoallergenic snacks with as few additives and ingredients as possible.

For cats, it's important to choose snacks that support health, for example by promoting weight control or dental care.

Checklist for responsible snacking

It can sometimes be difficult to know exactly how to snack responsibly with your dog or cat. Use this checklist to keep snack moments healthy and enjoyable:

Maximum 10% of daily energy requirements

Snacks should never replace the main part of your pet's diet. Keep them to a maximum of 10% of the daily energy requirement. This helps your pet stay in balance and prevents overweight.

Adjust snacks to age, weight, and health

Not every dog or cat can have the same snacks. Match the choice of treats to your pet’s life stage (puppy, adult, senior), weight and any health issues such as a sensitive stomach, food intolerances or dental problems.

Watch for signs of weight gain, dental or digestive issues

Pets often show subtle signs when treats don’t agree with them. Watch out for signs such as:

  • Reduced waistline or less interest in exercise
  • Bad breath, tartar build-up or difficulty chewing
  • Vomiting, diarrhoea or irregular stools


For cats: small portions, no milk or biscuits

Cats are sensitive to extra calories and to certain foods such as dairy products or biscuits. Opt for small, low-calorie treats that support dental care or weight management.

Remember: treats are no substitute for a complete diet!

Always keep in mind that treats are meant to be complementary. The main diet must be complete and balanced so that your pet gets all the nutrients it needs.

This ensures that snacking remains a healthy and enjoyable reward for both dogs and cats!
