Is your dog's collar too tight? If you can not easily place two fingers inside your dog's collar, it may be too tight for them. This is uncomfortable and can cause a number of problems for the pet. Visit your local dog care center to get a new and comfortable collar and check it often for its sizing.
Crates are a training tool that your dog will love. As part of your daily dog care routine, get your pet used to spending some time in the crate. Since dogs are den animals, they will naturally feel at home in these crates anyway. Many pet owners place dogs in crates to keep them out of trouble, but the dogs do like a place that is all their own.
