Bagira, a Great Dane, is feeling jealous because his owner is giving attention to a new puppy in the family. Bagira growls at the puppy and begs for attention from his owner. Jealousy in Great Danes can occur when they feel their attention is divided among other family members or pets. They need exercise, positive reinforcement, and training to feel like a valued part of the family. While Great Danes can get jealous, they are usually not as possessive of their owners as human infants can be. To stop jealousy, provide activities and teach them what makes them happy. Great Danes can also be aggressive, but all breeds of dogs can show aggression. Taming aggressive behavior includes providing exercise, training, and positive reinforcement. To calm a Great Dane, spend time playing with them, give them exercise, provide a safe place to relax, and offer distractions. Training a dog not to go after other dogs involves teaching basic commands like "sit" and "stay." Great Danes can make good household pets for families in urban environments, but the decision should be based on individual needs and lifestyle. Great Danes are not usually jealous of babies, but they may need supervision around small children. Before getting a Great Dane, be prepared for the commitment of training, exercise, and care they require.
