Little Miss Charlie came to us very pregnant. On Mother's Day 5/10/26 she had 9 beautiful babies who have all now found their homes and its Charlie's turn now. She came in heartworm positive and has completed the full 3 shot protocol for treatment of them. She will need to be kept calm for a few months. Leash walks and no free running around. She loves all humans and has had no issues with the other dogs or cats here. We do not know how she would be with kiddos.  ##2859668##

Story
Phoebe is a definite Rat Terrier mix around 3-4 years of age. She was found running at large with little Rachel in Taney Co. Missouri. She is a little shy at first, but a super sweet girl. She does climb out of the pup pen that is 4ft tall so a secure yard for her to play in with a privacy fence would be great! She is a little alpha acting with other dogs, but does like their company. Active girl and super pretty too! She would make a great trail/walking partner and prefers women over men, but does warm up. ##1734559##

Good with dogs, Good with cats, House-trained, Spayed or Neutered, Shots are up-to-date,
Story
Margarita is a sweet, shy cautious introverted young lady who is full of joy and love once she is settled and trust you.   We are unsure of her history as she came to rescue from someone who had just gotten her from another situation.    She doesnt like loud noises or fast sudden movements, and will take a while to warm up to people. Once she does accept you she likes to play and get loves. She Loves Loves LOVES food and treats. She is more comfortable and happy with dogs her size then people. She does ok with cats, she likes to try and play chase with them, so if the cat is open to 4 legged games. Her current bestie is a poddle mix and they run and play it, wrestle with each other, use the house and yard as a race track, steal toys from each other and generally just bring joy and mayhem together.   She does great in the car but is slow to learn the leash, outside her space is a big scary place so patience and a fully fenced in yard is a must. A home with no small kids would be best, but with at least 1 other dog is preferable.All pets are spayed/neutered, microchipped, up to date on vaccinations and on a flea/tick preventative.  Cats are tested for FIV/FeLV and dogs are tested for heartworms. Adoption fee is $150 for cats and $200 for dogs. To meet this pet, please fill out a dog application or cat application.  Not able to adopt?  Inquire about fostering or sponsoring this pet.  For more information visit www.allpawsrescue.info.  November 2, 2026, 12:17 pm
