I always had animals in my home: dogs, cats, rabbits, turtles, a ferret, hamsters… All of them rehomed, so I know how to handle them, understand them and, the most important, love them.
At the moment I'm living with my red collie who is lovely but a bit dominating at home, for this reason I can't take care of any animal in my place. I will be sitting at owners house, I can go to your house as many times as necessary to feed and/or walk your dog (or any other pet that you have). I also can put vaccines or give oral medication.
He/she will be treated as if was mine, with a lot of attention, cuddles and love.
