Sorry for the long post, but I'd really really appreciate any advice
My Shar Pei, Gypsy, is around 18 months old. We picked her up from a Shar Pei rescue centre in Melbourne (so she's spent time with lots of other Pei's). She's a little small for a Shar Pei, but generally a lovely, really placid nature.
Unfortunately, we've only had the chance to socialise her with a couple of other dogs - mostly just brief encounters while walking her (one didn't go well when there was a bit of a snap and snarl between her and 3 labradors, but nothing serious). When walking her she always gets real excited and pulls hard when she sees another dog, and we are going to take her to classes but we just haven't had the chance yet.
We've had to head back to stay with my partner's parents for a bit, and Gypsy has had to come with us. Only problem is, the parents have 2 dogs - a labrador and a staffy. Unfortunately, last night when we arrived things went a little awry and instead of the controlled meeting we planned, both of the other dogs came inside at once. The combination of 2 dogs wondering who's in their house, and the smaller Pei being intimidated when 2 larger dogs are in her face sniffing her meant that the outcome was inevitable. Not sure who snapped first - may actually have been Gypsy, but there was a fight between the 3. She has a few small wounds but nothing serious.
While Gypsy was locked in our bedroom, when she heard the others out the back this morning she got very, very anxious.
We just tried a controlled meet with the labrador (who's the more placid of the two) by bringing only him inside to meet Gypsy, and had them both on leashes in case things went bad. Eventually we released the leash and gave them time to investigate each other. His tail was mostly wagging but seemed unsure of what to make of her. Her tail wagged a little, but mostly seemed very tense, and after a while just wanted to hide behind/beside us. The fact that the lab likes to mount other dogs doesn't help - gypsy may well have snapped when he did if we weren't there.
We haven't done a meet with the staffy yet, but she's the more boisterous one and the more likely to be aggressive.
Any advice on how to get them all to meet each other - and to get comfortable to each other? a 1 on 1 meet is one thing, but any advice on how to get her comfortable so she doesn't feel intimidated when they're both around her? And not feel like we have to constantly supervise 'just in case'
She's running around the house feeling quite anxious at the moment (like I said, she's normally quite calm).
We do have a thundershirt, but weren't planning on using it for this. We're here for a month, and while we may have other housing options we'd prefer to get this sorted out.
