Are mushrooms safe or dangerous to feed my dog?
Mushrooms are dangerous. Although only poisonous mushrooms are toxic to dogs, all mushrooms, including those safe for human consumption, may cause illness, including excess salivation, vomiting, diarrhea, abdominal pain and lethargy. Some dogs that ingest large quantities of mushrooms experience seizures and coma.
It’s best to err on the side of caution, so don’t give your dog any type of mushrooms. When outdoors, keep your dog away from mushrooms, especially if you see white spores or wart-like scales on the umbrella-like cap.
Gardens can be pretty dangerous places for dogs. If it’s a vegetable garden, dogs can consume tomato vines, rhubarb leaves and potatoes—all of which cause serious medical conditions, such as kidney disease, and even death. If there’s fruit in the garden, and if flowers are also grown, they can get into things like grapes, which are completely toxic. Honeysuckle shrubs are also poisonous and dogs are attracted to these flowers because of the sweet smell.
There are a lot of other “garden dangers” Onions and garlic contain thiosulphate, a poisonous substance to dogs. Garlic does, too—but because onions contain higher concentrations of thiosulphate, they are more of a danger than garlic. All variations of onions are poisonous to dogs, including raw onions, cooked onions, dehydrated onions and table scraps containing cooked onions or garlic. Common dishes containing onions that may cause illness in dogs include pizza, Chinese food and commercial baby food.
If your dog eats onions or garlic, she may develop haemolytic anemia, a condition where red blood cells burst while circulating the body. Gastroenteritis with vomiting and diarrhea are early signs of onion poisoning. Dogs affected by onion poisoning show no interest in food and may appear lethargic, weak and depressed. The red pigment from the burst blood cells gets passed to the urine, and your dog may experience breathlessness from the reduced number of red blood cells carrying oxygen through its body.
