Are you dating a teen dog? Give him some toys and a treat :)
You have to give it a treat.
to stop your dog from being clingy, you must be firm with it, push it away soon it will realise that you dont want it round you all the time.
You don't! You get to know them, get comfortable with them, and then you are less nervous. But hope that the "nervousness" doesn't go away. That's part of the beauty of it. Another idea is to gently bite your lip.
My interpretation of this question was how early can you get a dog neutered and will this stop them from being dominant. A dog can be neutered at around six months and it will often make them less dominant.
Daily brushing
You should take the dog to a vet who will give it medication that will stop the milk from being produced.
It is okay for your dog to play with your hands as long as this does not escalate to your dog being violent, which can be prevented by training your dog when to stop. Play biting is natural for dogs, so as long as your dog isn't really biting and your hands are being injured, then it is okay.
To effectively stop your dog from barking using whistles, you can train them to associate a specific whistle sound with being quiet. Start by using a consistent whistle signal whenever your dog barks, then reward them with treats or praise when they stop barking. With consistent training and positive reinforcement, your dog will learn to respond to the whistle and stop barking on command.
maybe youre dog is bored and needs a nother dog to play with.or,youre dog isn't getting enough attention...
it would make her stop being horny so to speak
You probably won't. The best thing you can do is to keep them separated.
give both dogs equal amounts of love
