We have had our Beagle Bruiser for two weeks now and the last couple of days he has been really grumpy with us. Growling and hiding under a chair. This is new to us he has been a really sweet dog until now. He is chewing on everything and my husband thought maybe the new attitude and the chewing are related. If he is just teething is there anything we can do to help him feel better? He has two chew toys and a Kong we give him when we leave but it does not seem to take his attention away from chewing everything else we own.
