Need Help please. Toy Poodle

Hello
My name is Viktoriya
I, myself love animals of anykind. When I can I do donate to spca or others, and I do sometimes provide them with food, cages, blankets, etc…
I do try.
I have four dogs. A old small female chihuahua, a Female American Toy Fox Terrier who was given by our neighbors, and a female Maltese Mix who was abused and was fed with drugs. We did rescued her and she still lives with us.

On December 25 I saw a small dog digging in the garbage. When my family tried to call it, it ran away. Finally in the middle of the night we caught it. She is a Toy Poodle and 7 years old.
She had a lot of fleas. I mean alot. We gave her 3 bathes. Her ears have an infection. Her front teeth and the bottom teeth are gone, and the rest teeth are yellow and black. The doctor said the dog does need a dentist.
The docter said the reason ehy her legs aren’t and why cant she walk normal was because she was kept in a medal cage only for breeding.
