No, dogs cannot eat pasta with sauce. For the sake of your dog’s health, Just keep it plain and simple. That is the rule of thumb in case you want to feed your dog pasta.
Pasta sauces are usually laden with ingredients that are toxic to your pooch. These are garlic, onion, salt, oregano, and cheese.
Garlic contains thiosulfate which is very toxic to dogs. When this compound is absorbed in the gastrointestinal tract, it causes oxidative damage to their red blood cells, developing into hemolytic anemia and eventual organ damage.
Even the powdered form of garlic is deemed toxic, so it is better to think twice before you give your pooch spaghetti with your favorite marinara sauce.
Onion is another thing to avoid. This also belongs to the same Allium family as garlic, leeks, chives, and shallots. Onions contain the compound N-propyl disulfide which destroys your pet’s red blood cells.
It causes anemia, as well as methemoglobinemia, a condition when there is no balance in the hemoglobin and methemoglobin blood cells. This results in inadequate oxygenation of your pet’s tissues.
Early symptoms of poisoning from eating too much garlic and onions are weakness, vomiting, and a pale mucous membrane. Take your pet immediately to the veterinarian if your pooch consumed excessive amounts of these ingredients.
The salt in your pasta is likely to trigger some health problems to your pet, especially if there is too much of it. Excessive salt or hypernatremia will cause the cells in the body, including brain cells, to release more water in order to balance out the amount of salt in the blood.
Symptoms include dehydration, vomiting, diarrhea, high temperature, seizures and sometimes, even death.
Another common ingredient in pasta sauces is oregano which could cause mild poisoning when ingested by your pooch. It is not deadly, but it can create digestive issues like vomiting and diarrhea.
Black pepper is also known to cause nausea, vomiting and diarrhea if taken in large amounts.
A lot of the cheese we put in our pastas can be harmful to our pooch like parmesan, gorgonzola, cheddar, or goat cheese.
Parmesan has a high sodium content like most hard cheeses and consuming too much of it could cause high blood pressure and obesity if given regularly.
Gorgonzola and other blue cheeses have fungi in them that can be harmful and bring about digestive problems in your pooch.
Goat cheeses like feta and brie, on the other hand, have high saturated fats that can cause pancreatitis.
Not to forget that most dogs are lactose intolerant and for some, even small quantities can result in adverse reactions.
What About Pasta With Tuna?
Yes, pasta with tuna is fine, but only when it is fed to your dog in moderation. Tuna is very rich in lean protein with lots of omega-3 fatty acids which is good for their coats, but excessive consumption is often unsafe because they may contain high levels of mercury.
