mygirllola - hers isn't severed, just lacerated, so she's structurally just fine and the tendon will heal back to full strength. Today is her first bandage change and I'm not looking forward to that... she's lethal with those hind legs if she has an OMG attack and I don't really want to be underneath her if she does.
I'm really lucky, her injury is mid-cannon so it's the best place it possibly can be and shouldn't scar too badly or pop the stitches. It came together really nicely when the vet stitched it [he probably got there less than 1/2 hour post-injury, it was very fresh when we found her - not even bleeding yet - so she has the best possible chance for a great recovery] so in actual fact the most likely place for a scar is if the tendon fluid blows out the skin a bit lower down.
It's also really easy to keep a bandage on. Her bandage hasn't slipped and today is day 3. If there was no tendon involvement, because it's been stitched and so the actual wound that has to heal is quite small, I probably wouldn't put another bandage on. I would keep it covered for sure using what we call "fixomull" which is basically a giant steri-strip, plus a sterile pad to keep the stitches from sticking to the dressing. It's just that with tendon involvement I want to support the leg as much as I can.
