all the information i have ive given to you her mobility in the last 2 weeks has decreased significantly and this is my worry i have an appointment for a second opinion as im not satisfied that they are acting in the best interests of my dog and also how we are axpected to find 950 for exploritary tests in the present state of the economy and she isnt insured either so i am very much in a catch 21 situation
Unfortunately older dogs do tend to experience a weakening of the hindquarters with some regularity...it's more obvious in some breeds (such as German Shepherds and Retrievers) than in others, but either way, it's hard to see your pet having trouble and not being able to do much about it.
It's hard to know if this is simple arthritis or if there is something more going on. Some dogs get spondylosis (which is a narrowing of the spine, which causes pressure on the cord that results in some rear end weakness), and some get osteosarcoma (bone cancer), both of which can present with rear end weakness.
Unfortunately, the only way to know for sure what you're dealing with is through an x-ray of her spine/pelvis area.
