Grooming Needs of the Bullmastiff

The Bullmastiff dog breed is a low-maintenance breed that has these grooming needs:

1. Brushing

Imagine this: you run your hands through your dog’s hair, and oops—tangles! If you don’t want this to happen, then you should brush your Bullmastiff at least once a week with a rubber curry brush. This will help you not only reduce shedding but also keep the Bullmastiff’s coat tangle-free. 

2. Bathing

Another grooming essential is to bathe your dog once every 2-3 months or if they look exceptionally dirty. But don’t just use any shampoo to clean them! Human products can cause harm to dog’s skin, which is why you should stick to dog-friendly supplies and products.
