Bring the pee pad or anything with their sent on it...(A paper towel with her urine or poo on it from an accident) to where you want her to go...Keep her on a SHORT leash, don't let her sniif EVERY WHERE or you will be out side for a LONG TIME...Sniffing to a dog is like a party!
Just keep the leash short, and tell her to potty. Make this your potty area... once they know it's potty time and they are at the potty area they will just go right away. Chewy has an enclosed potty area, once he sniffed it, he was done with sniffing and now he goes within 5 minute every time. (Shorter if he doesn't need to poop.
Sadie also has an enclosed potty area and she goes right away too....(She is 4 months) She still has accidents but if you take her potty she knows what to do right away!
