When it comes to dog crates or cages, you want to buy the correct size for your breed of dog. Cages are not just for carrying or transporting your dog, but more importantly they are used for house training, and this method is referred to as crate training. Having said that, buying a cage that is too big for your breed will result in him sleeping at one end and using the other end as a bathroom, defeating the purpose of the training.
Small dogs especially do well with crate training, although just about every breed both large and small has had positive results, and quickly too, when using the crate training method. The idea of crate training is that a dog will not go to the bathroom where he sleeps, of course there will be accidents, but if you take him out before bedtime and again as soon as you wake up, he will pick it up in not time. Moreover, it won’t be long before he can go a full 7 hours or more before needing to go, because their metabolism slows when they sleep.
One should only use positive training methods when crate training, allow you dog to become used to the crate in his own time, slowly at first, maybe put a favorite toy in the cage and a favorite blanket. Don’t put him in the cage and walk away the first time, stay in the room with him and leave the cage door open until he gets used to it being his area or den. Moreover, you can slowly increase the time you leave him in the cage until he is completely comfortable with it.
Whatever type of cage you go for, be sure that there is enough room inside for him to stand, turn around and lay down, but not so big that he has a big empty space at one end. Smaller dogs will need smaller cages and large breeds may need several cages during their growing stages. Never put a dog in a cage with a collar on, because this can become a choking hazard.
