Q: [header] How to teach your older dog basic commands [title] Use positive reinforcement. [step] Your older dog will be more motivated to continue learning new commands throughout its life, if you use a positive rewards-based method. Training with verbal or physical punishment can scare your dog and make training sessions less fun. <sep> (A) Instead, practice based rewards like putting the treats back in your dog's mouth or giving positive verbal cues like " good job! " or " well done! " praising your dog makes training even more fun. [substeps] Reinforcement training may be more suited to younger dogs than short bursts of positive reinforcement. (B) Instead, use positive reinforcement at the beginning of training with play and verbal praise. [substeps] For example, say' happy new week'. (C) 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. (D) [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.
