How to stop my 6-month puppy from biting and hurting my older dog?
Hello and thank you for your question. I'm sorry to hear your two dogs are having trouble. Biting behaviour in puppies is very common, but should always be discouraged. At this point it sounds like you'll have to separate the two dogs, at least when unsupervised, for the safety and sanity of your older dog You can gradually start to re-introduce them with close supervision, and only reward the puppy with treats and praise when she is calm and quiet around your older dog. You could even take a step back and have them sniff each other through a baby gate, while giving the dogs treats and praising them when they are calm together.
Everyone in the household will have to be on board with discouraging Clara to bite. This means that if she is nippy around other humans, you should give a firm "no" or "ouch!" and walk away or ignore her. If she consistently does not receive the attention she craves when she bites, she will eventually learn that biting does not get her what she wants.
I hope this helps, and that your two pups are getting along soon! Good luck!
