Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Male | neutered | 6.5 lbs

Adopted Female chihuahua on 7/31/17. He was very scared and bite 4 people while trying to put him in a crate. I was told the owner brought him to the shelter for aggressive behavior which is bitting. I have ideas of making a safe place for him to come home to. This shelter is a high kill shelter and he was to be euthanized the next day. Do you have any ideas of why he has become aggressive and what to do.

What a beautiful thing to do to adopt Joey Jax and give him a forever home, despite his issue. You are his hero. I can offer you some tactics to attempt, however, my best advice is that because we don't know what poor Joey Jax has been through to make him become aggressive, it would be a great idea to have an appointment with an animal behaviourist. They can monitor his reactions and analyse his overall demeanour and give you advice tailored specifically to Joey Jax. I also recommend a once over form a veterinarian to ensure there aren't any underlying medical conditions causing pain for example. Try the following; Exercise twice daily Reward positive interactions Stop interacting if any unpleasant interactions occur No harsh tones or striking as contributes to the problem No negative punishment Interactive games like fetch and hide and go seek Thunder coat Keep away from other dogs and people while you are helping him adjust Remember kindness begets kindness. So over time if Joey Jax is treated well he will expect kindness and therefore return it with kindness not fear aggression. The key is making him feel secure and loved. Best of luck with Joey Jax
