Onion is undoubtedly a food you should not give your dog under any circumstances.

It is a potentially toxic food due to its allicin content, released after chewing. The secreted substance will cause an oxidative injury in your dog, which will cause the rupture of blood vessels and consequently hemolytic anaemia.

If your dog has consumed a small amount in an oversight, you should not worry since the most serious damage will be caused by continued ingestion, such as gastrointestinal problems and even jaundice.

Do you think your dog has been able to eat onion? You will be able to tell if you have vomiting, weakness or a change in color in the dog’s mucus.

These great pleasures for us can lead to great intoxication, which is why they are considered prohibited foods for dogs.

What do they have in common? Methylxanthine is an alkaloid that acts on the central nervous system.

Coffee contains caffeine, tea theophylline and chocolate theobromine, all toxic substances in large quantities.

In addition to damaging the nervous system, they can also affect:

  • Kidneys
  • Cardiovascular system
  • Smooth muscle
  • Striated muscle

To give you an idea of the danger of this food, 100 grams of dark chocolate in a medium dog can be fatal.

What are the symptoms of methylxanthine poisoning?

Vomiting, diarrhea, incontinence and tremors.

What do I do if my dog eats chocolate or coffee?

The most recommended in these cases is that you cause your dog to vomit before the hours of its consumption.

How delicious are the nachos with their guacamole, huh?

Avocado is one of the vegetables prohibited for dogs due to its persin content.

It is a fungicidal toxin derived from fatty acids. Although its level of toxicity in dogs is mild, it is still a prohibited food for dogs.

Its toxin is found mainly in the bone and in the leaves and not in the meat itself; it is best to avoid any ingestion and even prevent the dog from playing with the bone since the dog may have an obstruction in the oesophagus.

The symptoms are very similar to the rest: vomiting, diarrhea, and the development of pancreatitis in the most serious cases.


is salt good for dogs

Pet owners prefer to prepare homemade meals for their dogs instead of buying feed for them.

The “problem” with this is that they use salt for its preparation without considering that it is a toxic food for your dog.

High consumption of this seasoning can lead to the dog suffering from dehydration, aggravating heart or kidney pathologies, and course intoxication.

What are the symptoms of salt poisoning?

  • Vomiting
  • Internal bleeding
  • Incoordination
  • Diarrhoea
  • Polydipsia and polyuria (constant urge to drink and urinate)
  • Seizures and shock.

So, if you are one of those who prepare homemade diets, be very careful with salt when preparing them.

The toxin concentration is higher in the grape seeds, and since the dog does not make distinctions when ingesting, it is best to avoid this food in the dog’s diet and keep them as far as possible from their reach.

In the end, they are like little children.

Who would have thought that cooked bones were one of the long lists of prohibited dog foods, right?

What does a dog like a good bone?

No matter how you have prepared them, You should NEVER offer this type of food to dogs. Why?

The bones can cause the breakage of the teeth, but when older, they can splinter easily, obstructing the trachea, perforations, tears and various other internal injuries.

A good substitute for cooked bones is raw, meaty bones.

We are not going to deny this pleasure to your dog.
