About a year ago, I wrote about this subject. It doesn’t do any harm to remind folks that allowing your pet to eat any of the following could, and often does, kill the animal. I personally know of two dogs that got hold of some grapes and both died. And another two that the owner found while they were eating them and managed to get the dogs to her vet in time to be treated. They were lucky to survive.
The following is taken from the K9 Magazine. Please read the whole article for more information.
The wrath of grapes was, unfortunately, all too familiar for many dogs and cats in 2008 as a US based pet insurance firm released data showing how many toxic claims it had dealt with last year. For many dog owners, they are unaware of which foods can prove toxic to dogs until it’s too late.
VPI pet health insurance analyzed the more than 400 claims it received last year for toxic plant ingestions to find which plants and plant products proved most likely to poison pets. Raisins and grapes topped the list, followed by mushrooms and marijuana. In 2008, the average amount claimed for plant poisoning was $427 (approx £300).
Top Plant Poisoning Claims of 2008
1. Raisins/Grapes
2. Mushrooms
3. Marijuana
4. Lily
5. Walnuts
6. Onion
7. Sago Palm
8. Macadamia Nuts
9. Azalea
10. Hydrangea
“Almost all plant poisonings in pets can be prevented, but prevention depends on knowledge, thus it is important for pet owners to become familiar with which items can be toxic if ingested,” said Dr. Carol McConnell, vice president and chief veterinary medical officer for VPI.
“Prevention is a simple matter of keeping these hazards out of a pet’s environment. To avoid plant poisonings, try not to give a dog table scraps that contain raisins, onions or nuts, and make sure that a new pet is introduced to a backyard free of sago palms, wild mushrooms or other toxic plants.”
Pet owners have good reason to take the threat of grape/raisin ingestion seriously. Even in low doses, ingestion can place pets at risk for acute renal failure. Symptoms include anorexia, lethargy, depression, vomiting, diarrhea and abdominal pain.
