We went out of town last weekend and we left Lexie and Sammy at a boarding kennel for about four days.. According to the owner, they did outstanding, however, ever since we got Lexie home she's been acting odd.. She's been sleeping really close to us, pretty much right up beside us! Plus, she's been panting ( probably spelled it incorrectly ) a lot! Could this be that she is nervous that we're going to leave her for a few days again or is this normal, boxer behavior? Just curious.. We've had boxer for years, although, this has never occured..
