The vet said it is a reaction to the stitches - no infection, drainage or inflammation. It doesn't hurt him at all. She had another vet look at it and they agreed - no worries. He has managed to charm everyone in the clinic. They had him in back and I heard them all ogling him and talking about how sweet he is. They don't have the bruises I have from him! He chomped on both of my arms this morning as he kept trying to get at something I was carrying.
I have reduced his food but he is hungry all the time anyway and now he just barks at me. I fill Kongs with dog food and then freeze them. That takes quite a while for him to get it out. He also gets marrow bones that are frozen. They keep him busy for a while, too. He also gets bones filled with cheese or filled with peanut butter - anything to keep him occupied. But, he is "short, attention-span theater" and no matter what it is, he doesn't stay focused for long. Typical German Shepherd. The vet told me to give him some Benedryl. As it turns out he needs to stay quiet for another 4 days, minimum. I give him a little calm training here and there to occupy his mind a bit (he gets bored way too easy!) but the confinement is tough for such an energetic little guy. I will be glad when I can take him out for a good, long walk and some fetch in the yard.
