My dog won't use the pee pad anymore.

If you haven't fully given up on potty training, I would say definitely try again! Many dogs double digits in the years can still be potty trained with a regular schedule, patience, and some close management. Treat her like a 10 month old puppy you just adopted - she doesn't leave your sight (otherwise - in a crate, or someone else's lap), take her outside as much as you can and just wait for her to pee, and reward like mad with treats/praise when she pees outside. You can even add a cue for when she's peeing (my pup pees immediately after hearing "Go pee pee!", or will at least sniff around to pretend to pee if she's already gone lol).

My personal preference is very against pee pads though. It's quite confusing for the dog to distinguish that peeing inside but on a certain type of surface is okay. It's a little easier to distinguish that outside peeing is wonderful and inside peeing is meh. I know I didn't directly answer your question, but hope this is useful. Potty training even at an advanced age will save you much more trouble in the long run.

Yes, the holder absolutely scares her. Dogs don't like to stay on something unstable. I got the holder before and returned it immediately, because I knew right away they won't step on it. It made floppy sounds, it somewhat moved when you touch it, no way they would come near it, it was uneven to the floor as well. So yes, absolutely remove the holder. It also depends on dogs but I think all dogs afraid of unstable, slippery flooring. Try scotching it to the floor, or get washable reusables, I absolutely love those. Try to find the one that look similar to the pads you use, I was able to find white with blue bottom, love them.

She might not be comfortable with the material of the pads. There are several other alternatives you can try by doing a quick google search. We invested in a patch of grass for the house and our pup loves it VS using the pad (more natural for them).

I recently adopted a puppy Chihuahua when I first brought her home it took her about 6 days to start using the pad on her own for about 3 weeks until 3days ago she all of a sudden stopped using her pads what is going on with her now please help!

Could you remove the holder to see perhaps if your dog will go back to using? That may help you answer if she is afraid of a new change. If she is, you could maybe consider using invisible tape instead of your holder.
