The time it takes to train a puppy not to jump on people or bite their fingers can vary depending on the individual puppy and the consistency of the training efforts. Generally, puppies have a shorter attention span and may take longer to learn certain behaviors compared to adult dogs.

Consistency and repetition are key in training a puppy. With dedicated effort and regular training sessions, you can start to see improvements within a few weeks. However, complete mastery of these behaviors may take several months of consistent training and reinforcement.

Here are some tips to expedite the training process:

1. Set clear boundaries: Establish consistent rules from the beginning. Teach your puppy that jumping on people or biting fingers is not acceptable behavior.

2. Redirect the behavior: When your puppy jumps or tries to bite, redirect its attention to an appropriate behavior. For example, ask your puppy to sit or offer a chew toy instead.

3. Use positive reinforcement: Reward your puppy with treats, praise, and affection when it displays desired behaviors such as sitting calmly or chewing on appropriate toys. Positive reinforcement encourages your puppy to repeat those behaviors.

4. Be patient and consistent: Consistency is crucial in training. Everyone in the household should follow the same training protocols to avoid confusing the puppy. Reinforce the desired behavior every time and avoid inadvertently rewarding unwanted behaviors.

5. Socialize your puppy: Expose your puppy to various environments, people, and other animals to help it learn appropriate social behaviors. Controlled interactions and supervised playdates can contribute to reducing jumping and biting tendencies.

6. Provide appropriate outlets for energy: Puppies often jump and bite out of excitement or excess energy. Ensure your puppy receives adequate physical and mental stimulation through regular exercise, playtime, and puzzle toys.

Remember, training a puppy requires patience, consistency, and positive reinforcement. Every puppy learns at its own pace, so stay dedicated to the training process, and you should see progress over time. If you encounter significant challenges or have concerns, it can be beneficial to seek guidance from a professional dog trainer or behaviorist.
