Seeking some help giving our 2 large dogs proper exercise while I’m currently very pregnant and unable to manage them for long walks on my own. They go for evening walks with my husband but would benefit from morning walks as well as they are both active breeds who love to be outside. One is a almost 6 year old golden retriever (70lbs) who is great on leash ever since puppyhood. Generally does not pull. One is a 1 year old Bernese Border Collie cross (55lbs) who we haven’t done a great job leash training with. He is stronger than he looks and pulls quite a bit on walks. He is not yet neutered which contributes to his strength and pull desire. Need to be strong enough to handle him.
