Poor you. I agree with MaggieR. It could have been the treats at the till or maybe even your purse/bag. I had Jade here the other day and I was doing a little (if flights to Oz are little
) Internet shopping on the iPad. I put my purse down on the sofa beside me, next to Archie. Jade walked past and he lunged and growled and grabbed the purse!! I hadn't even considered it would be an issue - lesson learned. It was easily resolved but it does go to show that this kind of unpredictable behaviour can be very tricky to pre-empt sometimes. Archie will also guard my bag from other dogs if I put it down and I know this isn't uncommon.
I very rarely take Archie into PAH with me. I tried a couple of times but he seemed quite worried in there. Tail down, ears down, no wagging, looking at me for reassurance. In my case, I think that because I was anxious and looking for possible danger situations, I wasn't helping him. In the end I decided the treat would be what I buy, not the visit to the shop.
Hope Jamie enjoyed his pigs ear. I'm sure he is very very sorry and won't do it again.
