When a Beagle runs after a smaller animal outside, such as a squirrel, it provides excellent cardio exercise
, if nothing else. It DOES mean that your pet will quite possibly have an instinct to chase after small animals even those that are in the home or belong to your next door neighbors. Owners who are shocked to see a mouse in their house are soon calmed down when their dog quickly catches the surprised prey. Those who have smaller pets such as hamsters, guinea pigs, bunnies, chinchillas or ferrets should take great care to keep them out of the way of this dog.
They often see any animal that is the same size as they are, or smaller, as prey and the chasing instinct kicks in. If smaller pets are kept out of reach, this can drive a Beagle quite crazy...as the drive to catch the prey will be there, so close yet out of reach.
