Exercise Needs: More Than Just Walks
This isn’t a dog that will settle with one evening stroll. Jack Russell’s need daily action.

Grooming and General Care
Jack Russells are relatively low-maintenance, but they do shed. Their coat comes in 3 types: smooth, rough, or broken (a mix).
Grooming Checklist:
-
Brush weekly (more in shedding season)
-
Bathe only when needed

Brush teeth 2-3 times a week
They’re clean, but their love of digging means they’re not always dirt-free.

Patellar luxation
