For a dog like this one
Affiliate links: it costs you the same. How they work (in Spanish)

AI image: the real product may vary Rubber brush for short coats
Short coats don't need an arsenal: a rubber brush in the tub and done — massage and de-shedding in one.

AI image: the real product may vary Front-clip (no-pull) harness
If the walk looks like water skiing, the chest clip redirects without hurting. It doesn't replace training, but it gives you control while training arrives.

AI image: the real product may vary Large orthopedic bed
For large gentlemen: a big dog's joints appreciate real foam, not a soggy mat.

AI image: the real product may vary Soft training treats
Tiny, soft and heavenly-smelling: in training you pay fast and often, not with a five-minute biscuit.
