Hoping someone can advise. My 6 year old retriever had TPLO surgery nearly 4 weeks ago. All went well and at the 2 week check up things were fine. She’s been confined to a small space and going out in the garden on a lead most of the time. For the past week we’ve been taking her on short lead walks (10 min) as per vet’s advice. On Friday she suddenly seemed a lot lamer and at times wasn’t weight bearing. I’ve been giving her metacam and a hot water bottle on the leg but she snarls when I touch what is clearly a sore spot. We’ll take her to the vet tomorrow to see what he says but can anyone tell me if this sort of setback is common? A friend whose dog also had this surgery described the recovery as “up and down” so I was hoping this fell into that description.
