Let’s take grapes for example. This juicy, sweet fruit is very popular, especially in the summer. You’ve probably wondered at some point “are grapes toxic to dogs” while eating some yourself.

Are grapes toxic to dogs?

The truth is, grapes really are toxic for dogs. Even though grapes are good for our health and contain a fair amount of vitamins K and C, grapes are quite dangerous for your pooch. Now, there isn’t a specific reason why grapes are toxic, but experts believe that the grape itself is the problem. So, usually with some fruits, the problem is the seeds or the peel of the fruit. However, with grapes, it won’t help if they are seedless or peeled. Ingesting grapes or raisins can lead to acute kidney failure in dogs, and even death!

Another problem with grapes is that some breeds, depending on the size, can eat one grape and become severely ill, and others can eat a dozen and nothing will happen.

So how do you know your dog has grape poisoning?
