How to stop my 3-month-old puppy from biting and peeing inside?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | unspayed | 3 months and 5 days old | 5.5 lbs

I have a 3 months old puppy a mix between Malteze and Shih Tzu. She can't learn potty training and she does everything around the home, also she bites our hands and legs every moment. Can you suggest us a technique to break this habit and do you thing it will change by the time? Thank you

I'm sorry to hear that you're having these problems with Ebby! Puppies this age can definitely be frustrating at times. We actually have a great article on the PetCoach website that discusses housetraining in detail - you can read it here: https://www.petcoach.co/article/7-rules-for-effective-housetraining/0 This should get you on the right track with teaching her to potty outside. If you still have questions about this after reading the article, feel free to post again - we would be happy to try and help :) Biting and mouthing are very normal behaviors for a puppy this age - this is how puppies explore the world, and how they instinctively want to play. This will resolve on its own as she gets older, but there are a few things you can do in the meantime to help. Make sure that Ebby has a variety of different toys to provide an appropriate outlet for this behavior - long floppy rope or fleece toys for tugging, plush toys for biting and carrying, and smaller toys or balls for chasing and fetching. You should also provide lots of different things for her to chew on, such as bully sticks, large rawhide chews, cow or pig ears, and puzzle toys such as a Kong stuffed with peanut butter. If you are playing with Ebby and she bites you, just redirect her to one of her toys and use that to play with her instead. If she bites your hands when you pet her, calmly stop petting and ignore her until she calms down again. This will get better as she grows up, as long as you are patient and consistent.
