I have a pure black german shepherd. He is having health issues concerning his joints. His hocks are swollen one noticably more than the other), as is his toe joints (which the vet says is very uncommon for a young dog). The pain seems to be most intense in the mornings. Sometimes its not bad, sometimes he cannot even get up. He is a young dog, only 3 years old so a degenerative arthuritus most common in older dogs is very unlikely. I brought him to the vet and they are currently testing for infection, lyme disease among other stuff such as the type of artheritus that is not related to age. They have also taken various x-rays. In the meantime, I would like to get some peoples advice as to what kinds of medicines or nutrients can be given for the swollen joints, or if people may have an idea as to what could be causing the problem. Thank you for any input.
