I used to worked at a doggy daycare/grooming for about three years. I've supervised groups of 2 - 10 dogs all different breeds and sizes. I've bathe dogs and cleaned their kennels when needed. I also fed and gave medications as instructed. I did have a bully breed who was about one and a half years old but had to give her away because my previous landlord didn't approve of her breed. I used to take her biking with me and exercised her before going to work and before going to bed. I am also experience with cats. I do have two of my own and taking care of cats wouldn’t be a problem at all. I would be available for most of the day and we can always talk about what works best for one another and your dog.
