Hi I have a 18week girl Staffordshire bullterrier cross Labrador, she has a little hernia but nothing serious been told as it hasn’t grown so they will take out when she is spayed. Basically she is loving and nice one minute and the next she is trying to bite and chew on you and if you tell her no and gently push her away say if she was chewing the tongue of your trainer she jumps on back legs and growl like she going to attack. She mainly changes when granddaughter been loud or tried playing/ Wound her up also she won’t have a bed or anything she chews it up so at the moment she has no bedding in cage which I don’t like

Again, it is very important to stay on top of this and find a behavior plan that works for you while your puppy is young as it is much easier to modify now that it will be as your dog gets older.
