My dog is having a second flare up from IMO being back on concrete. After the first flare up Dr Milton x-rayed his leg and the knee looked great per him. He looked at his hips also and they looked fine. Both flare ups came after being in the kennel full time again. This second time he was kenneled for two days in a row and stayed the night in the kennel. He shows his greatest tenderness when he has to walk on my gravel drive and much less in the grass. Has anyone else dealt with this post surgery? Fwiw it was a tplo and he has been off concrete for 4 months or so. his first flare up went away with rest and getting back in the crate. He has been back in training to a lesser extent for about a month now with no visible problems. He also trained pretty hard fri-sun this past week and showed no signs until today.
