maybe encourage him to chew toys more? hard ones like kongs etc rather than stuffed ones of course. my pups now, if they get given a toy with one miniscule bit of fluff or stuffing that can be pulled out they'll get it the other morning I woke up to my Holly girl barking a bit but it was just cows. but i looked out the back window and thought.. "wow, the morning frost is sure showing up all those funny spider webs on the ground.."
..pity it wasnt spider webs.
she tore up her big fluffy pillow..
the line of fluff went from..
the front porch..
down the side of the house..
around the water tanks..
all the way down to the back fence.. which is a good 50m or so away..
it was like, 6:30am.. freezing cold.. and i had to pick up tiny clouds in my pyjamas..;) but i still love her to bits, she just has a wooden box with blankets now
and my 2 boys, being country dogs now ;) have drums that they sleep in they love them so much!
