Hi can any body help i have a friend who has a 9 month old field labrador who is destructive in the house it is walked every day and he is well loved he goes in his create by night but my friend wont put him in it by day ?????????? i do this with my lab and he is great ive told him to do the same but !!!!! can any body tell me of any other way to control his behaviour please... thanks martin

Being walked is one thing, but is his mind worked during these walks, like chasing balls or doing field work out of the house? Being mentally tired they are less likely to be destructive. we have one who is 8 months old and until he was trained in and out of the house he was a pain and did chew and chew and chew.
How much time do they spend with him in the house? Not just being in the same place at the same time but actually playing games and training in the house as well? This can help to assist, hide and seek games are great fun as well. Get his nose really working and a huge rewards for finding it

Thanks for that i will tell him about it. he as asked me to have him tomorrow so i will take him up the field and get him to use his mind and nose.

> Get his nose really working and a huge rewards for finding it

Totally agree 

My Border Collie will take all the exercise he can get.  But, it isn't enough, he really does need to work that brain.  He loves me to hide things, and I have to make it more difficult as he progresses.  And I have never had a thing destroyed, so it's obviously the stimulation that suits his needs.

being destructive in the house when left can be because he's bored but also if he's stressed out about being left.  if they try and tire his mind out and also make sure that when they leave him it's done in the right way ie no talking or eye contact, just put him to bed and leave the room. the less of a big deal they make of leaving him the more he'll stay calm, as theirs nothing for him to worry about or get excited about. when they return they should also ignore him for a while, until he is calm.
