Welcome to YT! First, remember that accidents and chewing are a puppy stage, and they WILL pass!
Here are some of my tips on paper training:
-Bring her to the pad/paper several times a day-especially first thing in the morning, after meals, before bed, and whenever she wakes up from a nap.
-If she goes on the pad- PRAISE, PRAISE, PRAISE!!!!!!!! Throw a party, squeal at her, dance around-make a BIG deal of it, and TREAT!
-Feed her on the same schedule daily. This will help you to be able to anticipate when she'll need to go. Don't free feed-as then there is no potty schedule. Since she's small, she'll need to be fed several times each day-so make sure she eats enough and frequently, but do it on a schedule so you can figure out when she needs to go.
-Correct accidents ONLY if you catch her in the act. If you don't see her do it, you can't scold her. She won't remember anyhow.
-When you do correct her in the middle of going, don't yell or scare her, just a sharp "NO!" and then take her IMMEDIATELY to the pad, and say, "potty here" or something of the like. If you are too hard on her when she has accidents, she will start hiding it from you (can you tell this happened to us too?!
)
-As far as poo-eating goes, I have two poo-eaters. Though it's gross, my vet told me it's not at all harmful to them. There may be a reason she's doing this, though-what are you feeding her? Sometimes puppies eat poo because they're missing something in their diet, and/or they aren't digesting the food properly.
Best of luck to you!
