I have a pure breed pit bull who we have had since a baby, she is now 10yrs. We understand with old age come sore bones.... Kia had a major surgery in June due to a cervical infection. The surgery saved her life. Although we noticed her before the surgery crying when she walks up or down stairs it is now getting very bad where she dont want to go outside and pee. She has gotten thicker and if you even go to touch her backside around the top of her tail/ spine she crys. We think it's arthritis because of her age but would it Not effect her entire body? She also lives near the wood stove. We are not big on vets because of the cost and most time we have help our dogs more than we feel vets have. Any help with advise or diagnosis would be greatly appreciated.
