Buddy has a possibly torn ACL and arthritis, he's one of my dogs. The vet offered surgery right out of the gate (mucho dinero and she hadn't even scanned it) or watchful waiting and meds. Got Vet-prophen, which sounds like ibuprofen but isn't and can't be substituted, that's a buck a pill. Wanted to charge me $50 for a month's worth of glucosamine/chondroitin. Found it online for 19.99. The Vet=prophen is really helping so I might try to find that online cheaper and have my doc fax a script.
