How to stop puppy from biting older dog's face and drawing blood?

Using spray bottles filled with water or a loud noise such as coins in an empty can can be used to deter this behavior. Sienna could have more teeth coming in but this is likely just a behavioral issue due to her being a puppy. Many times this behavior subsides after growing into adulthood but some breeds may exhibit this behavior most of their life. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

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!

Your worry is very valid! It is best to make sure the two are only playing together when you can directly supervise them and that puppy and your older dog are separated when you are away so that an accident can't happen - even the most well intentioned of a dog can cause an injury! If the puppy starts playing too rough, a "time out" of a few minutes for everyone to calm down can also help and teaches your puppy that too rough of play is frowned upon. Diverting with treats and toys is also a great way, so keep that up.

Is the biting aggressive or puppy behavior? If you are seeing snarling, bared teeth, growling and then biting to the point of drawing blood, that indicates an aggressive approach and you should consult with a veterinary behaviorist in your area ASAP. If it is the typical puppy behavior, usually done with hopping and nipping, wiggly body, while playing, etc, then it seems that you just need more time and patience with Papi. Puppies explore their environment with their mouths, so making sure he has plenty of appropriate chew toys can help curb the behavior. If he does get too nippy, yelping loudly, and then getting up and walking away (and thus ending play) is best to help teach him that too rough of play ends the fun. You can then praise and give treats for times where he is quietly playing with a toy or with you. Puppies do go through a teething stage at about 6-7 months of age, so the chewing and nipping behavior can ramp up again at that time. Sticking with your training can help ensure the nipping behavior stays minimal.

There is a risk that the bites could cause an infection. Make sure to clean the wounds thoroughly and monitor for signs of infection. That is very concerning that the puppy is biting hard enough to make you bleed and you should consult with an animal behaviorist to help resolve this behavior before he is fully grown.

That sounds like a tough situation and I hate to hear this is happening. Most humans cannot correctly read canine body language without additional training. Unless you know what the dogs are saying to each other, it's impossible to know how to modify and train the dogs behavior. Canine aggression is a complex behavior as it can stem from dominance, possessiveness, fear, anxiety, resource guarding or a combination. I recommend to work with a professional trainer. This will give you the best and fastest results. Researching on your own will also be helpful. Familiarizing yourself with canine body language and dog training can help you to recognize what your pet is trying to say. You can find many books written on the topic and there is a trainer named Victoria Stilwell who I think is particularly helpful. Best of luck.

I have a couple recommendations for you in no particular order My first is to contact a different trainer because someone truly qualified will be able to help you out. Its crucially important to only work with a trainer who uses positive reinforcement and ideally is certified through the Karen Pryor academy or CPDT-KA (which stands for Certified Professional Dog Trainer - Knowledge Assessed). Spooky is at a great age to start training, and really it's mostly us humans who need to be trained. I recommend reading this free PDF right away: https://www.dogstardaily.com/files/downloads/AFTER_You_Get_Your_Puppy.pdf Finally, it sounds like Spooky is getting "egged on" by your loud noises and attempts to interrupt. He's probably finding it to be a super fun game that you two are playing. So, I would recommend taking the opposite pathway of totally ignoring inappropriate behavior. You mentioned that you tried this but he kept biting - you need to also move away and get space between you. You can use a leash or a crate, or a door to create space. It's very important to give Spooky an appropriate toy to work on when you leave the situation. This can be hard to do correctly, so use the above resources to help. I hope that helps a bit, good luck!
