" praising your dog makes training even more fun. [substeps] Reinforcement training may be more suited to younger dogs than short bursts of positive reinforcement. Ending2: Instead, use positive reinforcement at the beginning of training with play and verbal praise. [substeps] For example, say' happy new week'. Ending3: You can teach a variety of basic commands, such as " sit ", " down ", " stay ", and " come " to an older dog by using positive reinforcement. [substeps] For example, teach your dog to " sit " by holding a treat in your hand in front of the dog. Ending4: [substeps] Verbal and physical punishment may be misconstrued as verbal punishment, while physical punishment can be interpreted as verbal praise, such as petting or a really big smile. Other positive reinforcement techniques include giving your dog treats after it chews, rewards, and giving verbal praise to your dog after training.
