I have a 77lb dog who’s had 2 knee surgeries. It was months of carrying him up and down the stairs, holding his legs up while he potties, and lots of snuggles and love to nurse him back to health. I’m proud to say that they were successful surgeries! Hurt knees or not, he doesn’t have the nickname bulldozer for no reason so you can imagine the chaos that went on in my house! I have no problem with big dogs who just want to love on you as soon as you get in the door or who think they’re lap dogs even though they’re huge. In fact, I think that’s the best! I’ve taken care of my friends dogs as well as neighbors dogs while they were on vacations as well! I’m currently working part time and I’m getting my bachelors degree online so I have a pretty open schedule for your fur babies! Can’t wait! Your pup’s safety is my #1 priority. I would treat them they same way that I treat mine. I never leave the house knowing that there’s something they can get their paws into while I’m not there and I’m overly cautious about the doors being locked, the temperature in the room, them having enough food/water etc.
