Bambi, (approx 9 month female lurcher adopted from the animal shelter), and I, would like to introduce ourselves.She was abandoned and tied to a tree. She has been spayed and obviously has been trained to sit/fetch, she waits for her food until she is told, she is house trained, and though she pulls a little on the lead, she's ok on walks, and is sociable to other dogs, if a little boisterous. She has been with us for about a month, and is a lot calmer than she was.She gets two good walks a day and we have a large garden for her to play in. She has a worrying tendency to bark aggressively and show her teeth at my husband or me when she wants to play, or sometimes for no obvious reason at all except that she appears to want attention. She will pester us or nip at hands or sleeves. The only way to stop her seems be to distract her,but I dont want to reward her for her bad behaviour. We are attending obedience classes and hope that we can learn to train her out of this habit.
