In younger dogs, a dribble of urine is expected when they are overly excited. The behavior will likely disappear as your pup progresses into adulthood.
While it is less likely to be medically related, we should mention urinary tract infections can cause dogs to urinate by accident.
If your dog experiences incontinence, urine will, unfortunately, leak involuntarily. This is common in senior dogs and is experienced both while your furball is sleeping and awake.
Did your dog complete house training as a puppy? We all know the saying, you can’t teach an old dog new tricks. While your pup may appear to be house trained, peeing in your bed is simply not an option.
If your dog has lived harmoniously with you and has only recently peed in the bed, consider if there have been any new stressors.
