There are several reasons why a dog, such as a Jack Russell, may exhibit aggressive behavior towards cats. One possible explanation is that the dog has a strong prey drive, which can cause it to chase and attack small animals like cats.
Another possible reason is that the dog may have had a negative experience with a cat in the past, leading to fear or aggression towards them. Additionally, a lack of socialization or training can also contribute to a dog's aggressive behavior towards cats.
Whenever he sees a cat he will chase it and doesn't stop until he has it in his mouth biting it!
The use of a muzzle may help prevent the dog from biting, but it does not address the underlying issue. The dog's refusal to obey commands when seeing a cat suggests a strong emotional response, which can be challenging to overcome.
It is essential to consult with a professional dog trainer or behaviorist to address the dog's aggressive behavior and develop a training plan to help the dog interact with cats safely.
