I need some advice regarding my dog. She's a 6 year old

This answer was rated:

Hello, I need some advice regarding my dog.
She's a 6 year old Parsons Russell cross staffie called Merry and although she is very sweet to her human family, she is very fearful of other strangers and will bark and panic if they try to come near her and has become increasingly aggressive towards our other dog and reactive towards dogs on walks.
We have had a behaviourist in for her in the past and we have tried to follow what they told us in order to help her, but over the years the number of spats the dogs have had are adding up. On occasion we have been hurt in the crossfire and had to go to hospital.
Last night the dogs had a big fight and both had to be rushed to the vets. Merry had to have stitches on her eye lid.
We have been trying to keep them both apart today but she is now snarling when ever our other dog even comes near us.
I am thinking of having her put to sleep because we are just so anxious all the time, but I'm heart broken.


I am sorry to hear about Merry and her problems. My name is Rebecca. I am a veterinarian and will do my best to help.

Some information about the other dog may be helpful. Male or female? How old? Are both Merry and the other dog spay/neutered?

Heya, thanks for getting back to me. Muffin is female, 12, spayed and is a Parsons Russell. She is pretty much submissive to Merry. Muffin is a I love everyone kind of dog. Where as Merry gets very possessive over certain treats and her humans. Muffin sometimes hides under the table because Merry growls at her.Merry is also spayed. When she was spayed we were told she only had half a uterus if that makes any difference.

Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.

I am sorry but I am not able to make calls for the website. I can continue with you here, or opt out and you can wait for an expert who can make calls.

I was afraid you were going to say they are both spayed females. I am very sorry to say, that in my experience and in the experience of all the behavior specialists and dog owners and breeders I have worked with over the last 30 years, the fighting between 2 female dogs is the worst. "Bitch on bitch" aggression just gets worse, as you have seen, and eventually ends with one of the dogs rehomed or setting up the household so that the two never can be together. Eventuallly one of the two is seriously hurt, or killed. I really wish I had a better answer for you.

You can try putting head collars like Halti or Gentle Leader on both dogs, with leashes attached, so you can pull them apart whenever aggression begins.

The problem is based in pack behavior, and in the wild if two females decide they can't live together, one of them leaves the pack and finds or starts a new pack. Living in a home, they can't leave, so the fighting escalates. We know certain triggers for fights that can be avoided: going through doorways, food, toys, who gets the good bed (usually an elevated position like furniture). Not allowing them to get onto furniture in the other's presence, not allowing them to be off leash together around doorways , feeding them apart and picking up food before letting them out can all be helpful, but then you still them fight over something insignificant such as a tissue on the floor.

This is one of the hardest behavior problems with dogs, and no amount of training will make them live together safely. You can keep both dogs, but it means crate training them, and one dog in the crate whenever the other is out, only be walked on leash, fed separately, trying the head collars.

Let me know what other questions I can answer.
