MacDuff is an almost 15-year-old terrier mix who weighs 21 lbs and is very healthy but 2 weeks ago he injured his back right knee and we’ve been told he needs a unilateral TPLO for $5,000 with an estimated 8 weeks of recovery. I initially said yes but then started wondering if that would be the best decision. He can walk on that leg, although at times he is a little less stable when he tries to pivot. He can lift it to pee and still shows his usual joy and happiness. We bought a dog stroller and have been conservative with his walks….brief to allow his “business,” no running or sudden movements, no stairs, and we lift him up and down into the stroller, onto the bed, etc. I am more and more wondering about taking a conservative management approach and would appreciate feedback. I love my boy so much and would do anything for him but I don’t want to subject him to painful, major surgery with months of possible recovery if there are other ways to help him heal. PLEASE HELP.
