Do try out creative ways to provide your dog with food and water, other than training. Consider snuffle mats, food puzzles, scent detection games, agility training, impulse control and more.

Do bring out and swap out toys to keep your dog more engaged with them by creating a frequent sense of novelty when it's time for you to play together.

Do practice sharing and exchanging items that are of low value to them, before expecting them to do the same with something they may see as being high value.

Do register for private training so that your trainer can first assess your dog in scenarios where dogs aren't involved, to give you a proper understanding and tools about how to build up to the idea of other dogs being around, before jumping into a group setting.

Do lower your expectations, and work with your puppy in environments and around others that give you the room to make things easier for yourself as needed, before tackling scenarios your puppy is having difficulty with.

Do provide your dog with space so that they can on their own regulate their own emotions. If the environment does not allow it, consider that it is perhaps the cause of the behaviour and should be re-evaluated with a positive reinforcement trainer.

Do your best to not react too much, and wait for the nipping to cease before providing an alternative. If this is being done repeatedly, consider teething (for pups) or boredom be at the root of the issue and the unwanted behaviour is the symptom.

Do your best to avoid the behaviour, say "Yes!" and reward when your dog isn't jumping or begging.

Do attend doggy play sessions where you can reward your puppy for slowly taking space from you.

Do invite your dog to go into their crate when you know they're feeling tired, relaxed and like resting.
