We all get busy but leaving your dog alone for more than four hours every day can have a negative impact on its happiness, behavior, and quality of life. In fact, some dogs can eventually develop separation anxiety. Dogs are capable of feeling bored out of their minds just as humans are. When they become bored, they may start to wreak havoc on your house, or annoy your neighbors with endless barking.
If you can't afford doggy daycare or you want to help your dog feel more comfortable during times he has to be alone, then you can train your dog to become more comfortable when you're away.
The best time to start training a dog to be alone is when you first get him. Practice leaving him alone for a minute or two in the beginning. Gradually increase the amount of time you leave him alone and pay attention to his behavior as you do. Has he torn something up by the time you return? Did he potty inside the house? Could you hear him whining or barking through the door when you returned?
You won't want to increase the time until he's stopped the negative behavior. Don't enter the room if your dog is whining or barking because this will reinforce the behavior. Wait until he's quiet and then walk into the room praising him in a matter-of-fact tone. It might be tempting to coo at him and give him a treat when you return, but you want him to know that being alone is normal.
You may give him a treat before leaving but not upon returning. Never leave your dog alone without giving him something to do, such as figure out a food puzzle or find his favorite toys. You should also increase the time he spends with other dogs, whether that means taking him to doggy daycare a few times a week or scheduling pup play dates.
