My 15 months old Lab is chewing everything.

Hello. This indicates your pet could be going through either stress or anxiety or sickness. Sometimes even to gain attention of parents, dogs chew on everything in sight. Firstly, make sure your pet isn’t going through any illness. Secondly get him some toys, to divert his mind towards them. Thirdly, give him/her lot of attention and care. If doesn’t subside, go for training.
