My 11 yo mini poodle is diabetic and blind for a little over a year. We’ve been giving him his insulin shots for the same amount of time - twice daily. Recently, he’s been very sensitive and pries away or yelps a little when I give him his shot. I am now anxious about going near him because I’m afraid of hurting him. I’ve tried to alternate his injection sites but he still does not like it. I’m going to visit our vet again and see if he can give me a reference site for injecting him. I would like to know if it’s very common for dogs to experience this after a year or more of being injected and how do other dog owners overcome this anxiety.
