Baby gates
Many owners wisely use baby gates to restrict their dogs to certain areas of the house. Bedlingtons are very athletic, and if a stranger comes to the door, they might be tempted to climb the gate. Baby gates that allow a dog to get a toe-hold, and clamber over, are NOT desirable. They lead to dogs learning to scale the gates, and also present a danger should a toe get caught in the gate. Instead, gates with straight vertical posts and no mesh or diamond patterns are much more desirable. Several nice gates of this design can be found at Care-A-Lot Pet Supply.
Balls
I recommend soft squeaky latex balls, or balls of rubber that can be squeezed. No hard plastic balls, no tennis balls. Some Bedlingtons are fanatical "ball dogs" - I know, I have one! Hard balls can wear down the teeth. Tennis balls are great fun, but Bedlingtons can strip off the outer felt cover with their powerful teeth, and they are also hard enough to cause tooth wear.
Toys
Toys that can be stuffed with treats are a great idea as they engage the dog's mind while they try to extract the treats. Kong brand toys are designed for this. Stuffed latex squeaky toys are a recent addition to the market, and I have found them to be more durable than hollow latex toys. Another great new toy is the "unstuffed" line - these resemble critters like foxes, rabbits, etc, and have a few squeakers in them, but no stuffing or batting. My dogs have enjoyed a few of these without tearing them apart, the typical fate of a stuffed plush toy at my house.
