I have a 10 month old pup who is absolutely wonderful except one thing, I'm not sure if it's just a puppy thing or a behavioural thing what needs attention.
He randomly does a sort of whine noise then lunges to nip towards your face. Often it's when he's over stimulated but sometimes he will just be laying on the floor then he will make the whining noise and then his will lunge at whoever is closest to him. We know the whine and so know what he's about to do, but it worries me that he will do it to someone else.
For background, there are no children in the house, he's generally very friendly with people and other dogs. He's been doing this for about 3 months.
He's our first dog. Any advice appreciated thank you.
