You might want to hold off sharing that guacamole with your doggy. No matter how good you think guacamole is, you shouldn’t give it to your dog. Avocado contains a toxin called persin. It can cause upset stomach, breathing difficulties, diarrhea and fluid buildup in the chest.
Grapes and raisins are often used as treats for dogs but it’s not a good idea. Although it isn’t clear why but grapes and raisins can cause kidney failure. Even just a small amount can make your dog ill. Repeated vomiting is an early sign. Within a day, the dog can become lethargic and depressed. The best prevention is to keep grapes and raisins off the counters and other places your dog can reach.
