I have experience taking care of senior dogs (my foster parents had a senior pug— he was great!) and puppies as well (I have cared for my husky since he wad 8 weeks old— he is now 2 and a half!). My dog has a lot of energy so I have seen the full spectrum— I have even had experience walking my brother’s pitbull. She was very strong and loved to tug on her leash but I am also great with training now that I have had my dog for a few years. I would be able to host pets on the days that I am not working! So at any day besides those listed on my calendar! Many days I take my dog to swift run dog park for a few hours so he can play with his friends and get some good socialization! On the days we don’t do that, I usually take him for a walk lasting 40 min - 2+ hours (times are particularly longer during the spring/summer months). There’s always food and water available to him because he self regulates his food intake, but I know other dogs may need limited food intake so I would be cognizant with that!
