My little prince, a miniature poodle had surgery on his little leg. Poodles are bad about getting bad knees. All three of mine Candy, Toby and Prince have had knee surgery. he's in a wrap, not what you call a cast, but it sure looks like one. He will wear the wrap for 14 days and then we start physical therapy for a few months and it will take about 1 yr. for it to heal completely. Then we have to have surgery on the right knee, repeating it. I am so sad for my baby. It's expensive too. With 3 poodles, we have had 5 surgeries and another one next yr. That will be the end, we pray, of the surgeries for them.
