Hello. You are describing a pretty sick dog & there are just too many variables to even begin to narrow down the causes. This could be infectious, parasitic, inflammatory, metabolic, neoplastic or even more. So you see, the very best you can do for your companion is to see your veterinarian as soon as possible. The sooner your friend is seen, the sooner a diagnosis can be made & treatment started. Hopefully, your companion will be well soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
