If your puppy is not giving you his paw when asked, there could be a few reasons behind this behavior. Firstly, it is possible that your puppy hasn't been properly introduced or exposed to this command yet. Puppies need time to learn new behaviors and may not understand what is expected of them initially. Additionally, it is important to consider their age and developmental stage - some puppies might be too young or physically uncoordinated to comfortably offer their paw. Lastly, if your puppy appears hesitant or fearful when you try to touch or handle their paws, there might be an underlying issue such as pain or discomfort that needs addressing before they feel comfortable extending their paw.
