Jumping is a common behavior in dogs, but it can be problematic for some owners. While jumping may be harmless fun for your dog, it can be dangerous for people, especially small children or elderly individuals who may fall and hurt themselves when knocked over by an enthusiastic dog. In addition, jumping up on furniture or counters can lead to unwanted behaviors like begging or raiding the garbage. Finally, some dogs jump excessively out of excitement or anxiety, which can be frustrating or even scary for you as the owner. If your dog is displaying any of these unwanted behaviors, it's important to work with a trainer to help them learn how to appropriately greet people and control their excitement level.
