I own a JRT, Mason - he's 9. He is object and animal aggressive.

Customer Question

I own a JRT, Mason - he's 9. He is object and animal aggressive. I had two other dogs and had to send one to a family member due to masons aggressive behavior. The other dog a chihuahua, I have to keep them separate 24/7. Due to Masons aggressive behavior I can't board him or have him attend doggie day care, or go to dog parks. Over the years I have sent Mason to two board and train facilities. The most recent in January 2015. It hasn't helped and seems to have increased his anxiety level, it was E collar training.
I have had mason on an adoption website for 6 months but due to his aggression and need to be the only pet I haven't found him a new home. I looked at JRT rescue but they are either full and won't accept aggressive dogs. I worry about his fate with someone else. I am now considering surrendering him for Euthanasia. With Masons history would a vet put him down?

Hi Customer,
My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
The problem with sending a dog to be trained is they don't end up seeing the owner as the boss or leader. They see the trainer as the boss. I is important for an owner to do the actual handling of the dog during training and work with him every day even after a "training" program has been completed.
If he isn't neutered, have that done though it won't stop the aggression, it may help with any aggression due to reproductive issues like competition for a mate.
Terrier were bred to be hunters so catching birds is not unusual and would be hard to stop. However, you can try. So let me give you a site that goes over obedience training. The following site is helpful. Be sure and click on the link to the page on obedience at the bottom. and links on subsequent pages leading to detailed instructions.

.
Training works best if you train at least 30 minutes a day (two 15 minute sessions). I would start making your dog work via the Nothing in life is free program (NILF). It is outlined below.

A muzzle can help prevent him from attacking other dogs as well and would be a good idea for those times you are walking him or he is around other dogs or outside. It has to be a basket style muzzle so he can drink and eat and breath relatively normal.
There is a training program BAT that can help with dog on dog aggression as well.

The other thing that should be checked is medical conditions that can cause aggression such as hypothyroidism. Read more on these here:

If you choose to euthanize your dog, a vet willdo it, though I would expect the vet to try and talk you out of the procedure if it is strictly for the reasons mentioned and the dog is not people aggressive. If he progresses to being aggressive toward humans, animal control will usually seize them after a second bite and take the decision out of your hands.
I hope this information is helpful to you. If you need more information or clarification, please reply and I'll get back to you as soon as possible. If you are satisfied, please take the opportunity to rate.
