Frequently Asked Questions
Are Jack Russell Terriers good family pets?
For active, experienced families with older children, yes. They're not ideal for households with toddlers, small pets, or owners who want a calm dog.
How much exercise does a Jack Russell need?
At least 60–90 minutes of vigorous daily exercise plus mental work. A walk around the block doesn't satisfy this breed.
Are Jack Russells good with cats?
Generally no — their prey drive is intense. JRTs raised with cats from puppyhood may tolerate them, but small pets are usually unsafe.
