Hi there I am new to the forum and was looking for some advice. We hve a patterdaleXlakeland terrier 14 weeks who has a very strong bite. We have had him nearly 6 weeks. I am aware that puppies bite and some are more nippy than others due to instinct and breed. Our puppy is biting, holding on and growling and pulling. We were advised to ignore and walk away. This worked for a couple of weeks however it has escalated again this time worse. The ignoring doesn’t seem to be working and also we sometimes can not get away as he will not let go. Does anyone have any tactics I can use? Also I am concerned he is going to be very aggressive. Anybody have a similar situation and now has a well behaved patterdale? Sorry for long post first time owner as well so very confused with all the information out there. Thanks in advance.
