I am sorry for your loss here, my friends who are multi generational dairy farmers have a khaki who survived a mink attack, he has a permanently crooked neck and hobble, looks like Quasimodo, but he gets around just fine. The afore mentioned dog pen my wife came home with for our (now 10 year old) yellow lab puppy, I laughed, she could jump it or knock it over in a second. It is the best thing ever. Many puppies have been contained while camping, ducks, chickens, injured cats have been kept in it, way better than a cage and it folds up very compact.
Hang in there , he will heal and will rejoin the rest soon.
Go get you a pen! Maybe 2
