Toxic foods for dogs are a real danger. It is not easy to turn down a wish from your beloved dog. But when it comes to food, you should be consistent. Of course, your dog would never say “no” to these foods because they smell so good and taste amazing. Nevertheless, it is important that you avoid toxic foods for dogs. In this article, you will find out which foods are particularly toxic and what the typical symptoms of poisoning are.
Typical symptoms of poisoning in dogs

First of all, we would like to acquaint you with some of the symptoms that can indicate poisoning in a dog:
- Fever/hypothermia
- Diarrhea
- Vomit
- Excessive salivation
- bleeding from the mucous membranes
- Conspicuous/atypical behavior
- Attacks of weakness or fits of rage
From what amount of feed is poisoning possible?
A distinction must be made between toxicity and harmfulness, i.e. the risk of disease in certain organs after frequent eating. Some things are deadly immediately, while other foods only cause more damage after a certain period of time. Ultimately, it is no different than in humans. For example, the popular bacon is also very unhealthy for us due to its fat content. In dogs, fried bacon can lead to metabolic diseases and also damage the kidneys and pancreas. The breakfast bacon, which is apparently so tasty, should by no means serve as a treat for your beloved four-legged friend.
It is not possible to say how much of a food is harmful or deadly for a dog, as this depends on age, size, and previous illnesses as well as the food itself. However, one thing is clear, only with a healthy and dog-friendly diet can the four-legged friend stay fit into old age.
What vegetables can a dog not eat?
For example, dogs are not allowed to eat onions, garlic, raw beans, tomatoes, or raw aubergines.
Be careful when walking
Unfortunately, most serious poisonings occur while walking. The dog is out without a leash, runs ahead and finds something to eat there. As the owner, you often don’t notice anything and you later wonder why your dog is doing so badly. We recommend that you carry out a very consistent education here in order to avoid worse poisoning. In addition, our society is still affected by “dog haters”. They intentionally poison or injure the dogs with poisoned bait, which they hide in a piece of liverwurst or a bun, for example. Keep your eyes open when walking to avoid such accidents.
Contingency plan
If for any reason your dog has eaten toxic food, it’s important to act quickly. Every vet has a telephone hotline. Save this number so that you can call them directly and ask for advice in the event of poisoning. Don’t be afraid to drive your four-legged friend directly to the veterinary clinic. They will help you directly and will probably be able to prevent worse things from happening
