Our new puppy - small poodle cross - is 10 weeks old. She is DD's (8) puppy. (Obviously I know that I am really the one who is responsible.)
She has recently started growling, then snarling and finally this morning nipping DD when she picks her up to put her in the garden for a wee or gets her out of her crate; ie does anything which the puppy hasn't decided to do herself. Puppy has tried it with me once or twice, but far less. Puppy also guards her food.
Our old dog is gentle and submissive and I have never had any problems with her, nor has DD.
What can we do to make sure that this behaviour stops?
