I have a seven year brindle Boxer named Hershey. He is like my son. Over the past month my husband and I have been extremely concerned because he is loosing weight. His belly is getting larger. This all started last month when he startede what seemed like an asthma attack. He would dry heave but nothing would come up. So my husband and I took him to the vet and because Hershey has allergies he gave him a steroid shot and perscribed Hydroxyzine for him as needed. He also gave me vitamins to put in his food because he was starting to loose his hair. Now we are taking him to the vet in a couple days, but I am very scared because I am afraid what they are going to tell me is wrong with him. He has lost a severe ampount of weight all of the sudden. He also has been having a lot of accidents in the house which is not like him. Can anyone help me?
