I'd be interested to find out if he returns to his old habits when returnig home. I'm beginning study into canine behaviour and dog training. One of the things i'm interested in is finding out if its better to send your dog away or whether its best to deal with the issues in the enviroment that causes them. If he doesn't know his boundaries its possible they have been put accross in a language he doesn't understand (dog language) I have 2 dogs and 2 young children. The dogs are not allowed upstairs or on funrniture. The children are not allowed to feed tit bits to the dogs at meal times and if the dogs beg they are removed from the room. The dogs are only allowed in with the children when myself or my husband are around to monitor the situation. The dogs do not jump at the children if they do because of their height the children have learnt to turn away from the dog and say no or in the case of my 1yr old make a loud sound. The dogs do not get petted until they have calmed down and all 4 feet are on the ground. This may seem like tough love for the dogs but we have harmony in our home and the dogs know as soon as the children are in bed its their time with the heads of our pack.
