We have 2 Siberian Huskies and 1 Golden Retriever. We got our youngest Husky, Gracie, from a Husky rescue and she's a doll. She and our other Husky, Mya (who we got as a pup) get along great, play, wrestle, etc. We didn't know if Gracie had been spayed when we got her, but realized that she defintely had not when she went into heat. We didn't notice any major behavioral changes in Gracie while she was in heat. However, since we brought her home from the vet after being spayed, she's shown signs of aggression towards Mya. The first day or so, she was fine (she mostly just slept), but now it's been a couple days and she snarls at Mya and actually attacked her this morning when Mya tried to play with her. Mya is naturally more playful and energetic than Gracie to start, however I'm a little concerned. Gracie's shown no signs of aggression to our Golden. I'm hoping it's just a temporary change in her personality due to the surgery or hormonal changes. Any thoughts?
I can assure you her 'aggression' has absolutely nothing to do with the fact that she is now spayed. Considering Gracie is a few days post surgery, she may be a little sore and the last thing she wants is Mya in her face.
It is best to keep them separated for a full 7-10 days (it is advised to allow Gracie to rest in her crate). You should not allow Mya to initiate play at this point. Gracie is supposed to be kept quiet during her 7-10 day recovery. You would hate for her sutures to rupture!
I do also have to mention that owning two female is tough. See how Gracie does once she is 10 days post surgery. If she is still showing signs of not wanting to be bothered it may be time to look for outside help. Two females (even if both are spayed) are known to be a challenge. Your best bet is to find a training facility that offers Family Dog classes. They specialize in multiple dog house-holds and help you to work out issues in the home.
