Ya, Stig, Rupert's looked like a pork chop when his dislocating kneecap was fixed. Had to take him to use the facilities (lawn) with a sling under his belly to support his weight, keeping the strain off his one bad leg. Two must be a real pickle. Hope you don't have a lot of stairs. I slept on the floor next to him for the first couple nights. He's good now, but rehab/ healing was a number of months. Hope Thais heals well. A dog's enthusiasm can set back healing, sometimes.
Coconut oil is meant not to burn so easily when heated. Supposedly, if your oil smokes at all while cooking, its been burnt, and should be discarded, as its formed carcinogenic compounds. Olive oil smokes at a somewhat low temperature, though I still cook with it, being careful not to overheat it. Coconut add a coconutty flavor to things, go figure. Not always the best combo.
