I agree with Phay,,I have 5 indoor cats,,have 2 aussies (one who is VERY prey driven,,she'd chase a bird to canada if I let her
) and 2 gsd's..
My existing dogs have always been fine with the cats ,,my recent addition , 10 mth old Masi, who is working lines,,well, she does love tormenting my cats,,who give it right back to her and by nightime she is Sleeping with ALL of them!
Not a breeder here,,but as to the OP's question if I was,,,there are alot of people who want an active puppy because they have active lifestyles outside of showing/working etc...When I did home eval's for rescue,,the one factor in my mind was "would I put one of MY dogs into this home?" That would be the deciding factor if I were a breeder as well..
Now if it's someone/family looking for a couch potatoe and I had this high drive puppy , no way no how
