Great post. My son was bitten by a dog once while at a friends house. He asked the owner if he could pet him, the owner was sitting right there and holding the dog. Callum reached out to pet him and in a flash got bitten on the eye. It wasn't serious, but really scared him. Afterwards we realised the dog had a toy underneath him and perhaps he was being possessive.
My boys keep asking me if they can be alone with our dog and I constantly have to tell them no. Joey has had some growling issues with our son but even if he didn't I dont let them alone together.
