matt austin, Texas 9/26/2013 10:46:42 PM Good article, just a few points from raising one or two of them myself. Most often people confuse needed to play and mental boredom. Aussie's needs mental stimulation. Meaning you can run 10 miles a day with them, and play fetch 3 times a week, and your dog will still act and be a trouble maker. A well conditioned trouble maker at that. This is because they love puzzles and finding solutions to them. If you have one that is why you chew toys don’t last long. (Ours would pick the stitching out of soft chew toys and pull out the squeaker.) We got her Nyla bones, hard to chew through. But the best toy ever is a puzzle toy; we got her a Buster Food Cube. Any place has them, best toy ever. Fill it with a high reward treat, and make sure to take it away after awhile, (they will work till its empty). But it will get your Aussie over the (getting in trouble phase, especially in its teenage months.) That is why training can be hard, (ever notice your dog looks away while you are training it) cause it needs a challenge, and a puzzle to find the solution to. Another trick is hide and seek. They love that one. For the guy who has a dog that chases his cats, create safe zones for the cat. (i.e. your bedroom, or where the cat eats,) As one Vet told me, never let your Aussie do something ONCE that you don’t want it to do again. But great article overall.
