Hi everyone. I am completely new here and looking for some advice. I realise this forum is for lab owners but having followed Pippa's methods to the letter, I very much respect her methods and advice so hopefully a springer question is ok! I have an 11 week old springer puppy from working parents. Everything has gone really well - sleeping through the nights, housetrained, sit and recall coming on nicely, doing lots of socialising with people and my two older dogs. However I have one problem that I am really worried about. Last week at ten weeks old she suddenly started snarling, growling and snapping at me when I picked her up. Not puppy growling (I have enough experince of dogs to understand the ferocious puppy growl) This was a full on lips curled biting hands, lunging at face etc. This happened for four days. Usually in the evening. Whilst I did not particularly like this behaviour, I put it down to a tired, overwrought and over excited puppy. Each time it happened I crated her and she fell asleep. Today however things have got worse. This morning, a visitor was playing with the puppy (gently and appropriately) and she turned on him with the snarling and biting. I quickly removed her and managed to calm her - at this point I wouldn't say she was tired. Later in the morning we took her for her very first run on the beach where we met a couple with three dogs, an old lab, a young lab and a twelve week old springer. All the dogs started playing happily. My puppy was appropriately submissive to the other dogs - but not excessively so and was happy to have a rough and tumble with the two younger dogs. Suddenly however she turned on the dogs, biting snapping and growling - the springer pup was obviously quite taken aback and frightened and the owners not very happy. I intervened and picked her up and tried to calm her but she carried on biting and snarling at me until I eventually managed to calm her. Can anyone advise me on this? I think I know how to deal with it in terms of calming her, crating and time out etc. But my concerns are more long term. Could there be some kind of health issue? Does this indicate true aggression in the dog? I feel as though this does not bode well for the future and whilst I love my puppy dearly I cannot face the prospect of an aggressive dog. Help and thank you in advance!
