Charlie

Rat Terrier

Male, Puppy

Riverside, CA

Size

(when grown) Small 25 lbs (11 kg) or less

Details

Good with dogs, Needs special attention, House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Charlie is a super sweet, well mannered, potty trained dog. DOB 10-21-23. He has allergies. I’ve tried a variety of foods to no avail. I rescued another dog 60 miles from me and that dog was housed with Charlie. I couldn’t leave him behind. I didn’t notice until I got him home & reviewed paperwork he was listed with allergies. The problem is his skin gets so hot he stinks and I’m super sensitive to smell to the point of nausea and vomiting. I’m sure someone with the means can get him vet help with this and resolve his issues but I can’t. He’s very energetic, I have a large property so he runs quite a bit and loves chasing squirrels. He learns very quickly and minds. When he’s done for the day he’s done and sleeps well. He loves to be loved but has an aversion to hands being close to his face. He readily accepts a leash and loves to go for auto rides too. He comes when called. He’s excellent with the other dog. He loves to play with toys. He will go after food. He’s great with my bird.

Wednesday

Rat Terrier Chihuahua

Female, Adult

Anaheim, CA

Size

(when grown) Small 25 lbs (11 kg) or less

Details

Good with dogs, Not good with cats, House-trained, Spayed or Neutered, Shots are up-to-date,

Story

I rescued Wednesday from the San Bernardino shelter in October, and she has blossomed into the sweetest little shadow. She is a 9lb, 3-5 year old cuddle bug who believes blankets are life and loves playing fetch with her stuffed She is a pocket-sized companion who knows basic tricks, walks beautifully on a leash, and absolutely lives for attention. If you want a dog who looks at you like you're the sun, this is her. Wednesday has a very high prey drive when it comes to cats. She fixates on my resident cat constantly, and despite our best efforts, she simply cannot share a home with felines. She needs a home where she doesn't have to worry about hunting the kitty. Her ideal match: - Strictly a feline-free zone. - She hasn't been around kids, but a calm home would likely suit her best. - She is about 90% potty-trained to go in the backyard. - Spayed, chipped, and all shots up to date.

Click Here to Sponsor Me! Adoption APPLICATION: Muttsinneed.org/adoption-application ** Application must be completed prior to a meet & greet. Our Adoption Process:Muttsinneed.org/adoption-process Meet Little Boy! This sweet 4-year-old, 15 lb pup has been through a lot but hasn’t lost his loving spirit. He came to us after being hit by a car and left at a shelter with a broken leg. Now fully healed and feeling great, he’s ready to find his forever home! Little Boy is affectionate, playful, and a big fan of both people and other dogs he's properly introduced to. He clearly knew love before and is extremely affectionate with humans. He knows how to use a doggy door trained and he also understands basic commands like “lie down” and even picks up on phrases like “time to go to bed”—he’s smart like that! Like many rescues, he’s still working on a few things. He can be a bit of a food thief if snacks are left within reach and is working on his manners when on a leash when meeting new dog friends. However, with consistency and setting clear expectations, he’s happy to play and gets along well with confident, dog-savvy companions. With time, he will make a great dog sibling (like in his current foster home) Little Boy would do best in a secure home (he can be a bit of a Houdini!) so a home without a yard or if you have a yard, minimum 5ft fence. He may try to slip past you at the door and is quite skilled at wiggling out of a harness, so a slip lead setup and vigilance during transitions will be key. In return, he promises loyalty, entertainment, and lots of love. Apply to meet Little boy at https://www.muttsinneed.org/adoption-application.htmlSeptember 12, 2025, 11:57 am
