My 2 month old jack russell is worse about going to the door than she was when i got her. how do i train her very fast or i've gotta get rid of her
Hi Kain Housebreaking a puppy takes time, patience and persistence. It's totally unrealistic to expect a 2 month old puppy to be able to let you know when she needs to go outside, or to control her bladder/bowels in any really useful way.
If a puppy is given consistent, patient training in housebreaking, he or she is usually fairly reliable about it by 6 months of age. That is 'average', some pups are quicker, others slower.
If you don't have the time or inclination to train this puppy, I would strongly suggest that you find her another home as soon as possible. She can't learn what you expect from her in a matter of days, or likely even weeks. It's a matter of repetition and learning by association.
