1. He is eating and drinking but because the two dogs are fed together sometimes it is difficult to say if he is eating more or less than usual. However, his weight at his last check up seemed to show that he has been eating plenty. I have noticed that their water dish needs to be filled up several more times a day than usual. It may be that Dolce the sick shar pei is drinking more water than usual, I have seen him do that one several occasions.
2. I am not sure about that, they are outside in a concrete area at the back and side of the condominium but they do take walks down to the beach and have been at the dog park a few times but I haven't seen anything myself.
3. Both dogs normally have excess skin on their hind legs, I felt them for comparison and I would say Dolce, the ill dog, has more fluid in his legs. I also noticed over the last week that the skin on Dolce's chest, neck, and front and hind legs seemed to be losing hair. He has been scratching his neck with his hind feet frequently and the skin in these areas does look thinner than on his back and other body areas. He also has an atypical odor to his skin in these areas, not the normal "shar pei" scent that they all have, it was different, it seemed more sickly.
4. When I press of his rear legs the skin returns to it's normal state before I pressed it. I checked it on Vinny his healthy brother and his legs had the same response.
5. I did notice while checking the skin press response that on Dolce on both of his rear feet between the last and second to last toe that he has considerable swelling there to the point that it almost looks like another toe without the toenail.
