I have 3 dogs but my third dog is always with me. You will be walking my two 32-40lb dogs.
The girl is Kai, a black lab-shepard mix, spayed. Super friendly with everyone.
The boy is Jack, a 1-year-old border collie, in-neutered. Afraid of people and dogs, sweetest dog though.
I have a huge yard which you'd walk around with each dog separately or together for 15 minutes with my expectation being you do that within an hour. I need that done a few times a day Monday's and/or Tuesday's. Feeding may also be needed as well as light training. No health issues just an allergy to grain. Jack is actually allergic, he just poops soup so no biggie if he accidentally eats something.
I have 2 cats, a parrot you need not worry about.
