Since I am a non pet owner, can someone enlighten me on something? I'm not posting this to be negative or a smarty cat, I just wonder if someone knows the answer. Yesterday while in Sweetbay, we noticed a man with a dog in his shopping cart. It was a small dog so he had it on a blanket in the top front part of the cart, the area you would put your crushables like eggs. The dog had. Service thing on him. (Sorry, I don't know,what these are called) It seemed odd that a dog would be allowed to be in a shopping cart. I went to the manager and asked why the dog would be allowed in a shopping cart and he said they are not, but when they tried to communicate with the man they realized he was deaf. They were not able to communicate that the dog was not allowed in the cart so they let it go. My question is....what could a little dog do for this deaf man that he had to bring him into the store? The dog cannot communicate for him and the dog doesn't know sign language. So why wouldn't one leave a pet home,that to my knowledge, cannot assist him with disability? Is it a comfort thing? I just wonder. Thanks for the insight.
