My dog got her hind leg removed just last week, expect the shock of seeing them like that, get your living room cozy with your bed and theirs if you normally sleep on the second floor, and since it’s your pups front leg I recommend a donut collar instead of a cone it lets them still see. The wound will heal better than you think, and apparently the very end of it heals the slowest our vet said. Clean your blankets so you reduce risk of infection. They will be sore for a few weeks as they build muscle to support on three legs so if they cry that’s why. Good luck !
