Story
WE ARE A TX-BASED RESCUE. THIS DOG IS CURRENTLY LOCATED IN TX AND WILL BE TRANSPORTED UPON ADOPTION. Please fill out an adoption application at haydudeequine.org Meet Athena 💕🐾 Athena is a 2½-year-old Chihuahua weighing just 6 pounds, but don’t let her tiny size fool you — this little girl has a heart big enough to fill a room! Athena has been through something no dog should have to experience. She suffered a head injury that left her with some permanent brain damage. Thankfully, she does not have seizures, but she does walk with an adorable head tilt and has a bit of a goofy, quirky way about her. Her differences only make her that much more special. Athena is good with other dogs and would love a peaceful, quiet home where she can feel safe and take her time settling in. She can be shy when she first meets someone, but once she realizes she is loved and safe, she warms up beautifully. And when Athena loves you, she loves with her whole heart. ❤️ Because of her tiny size and delicate nature, we are looking for a home without small children. Her ideal person will be patient, understanding, and willing to give her the time she needs to build confidence and adjust to her new surroundings. Athena may do things a little differently, but she doesn't let that stop her from being a sweet, loving little dog. She deserves someone who will see past her head tilt and goofy walk and recognize the amazing little soul underneath. If you're looking for a tiny companion with a HUGE heart, Athena may be your girl. 🥰🐶 🏡 Ideal home: Quiet and calm 🐾 Dogs: Good with other dogs ❤️ Personality: Initially shy, then incredibly loving 👧 Children: No small children recommended ✨ Special needs: Head tilt and neurological differences from previous head injury; no seizures

Story
Please note that this dog is currently located in TX and will be transported once adopted. Our application can be found at haydudeequine.org. 🐾 Meet Vaquero! 🤠 **Rat Terrier Mix • Born May 15, 2026 • 7 lbs of pure puppy perfection** ### Here's what the humans have to say about me: Please note that we are a foster-based rescue in TX. All of our dogs reside in foster homes in TX. We transport them to new states once adopted. **ALL ADOPTERS MUST BE 21+.** Our adoption application can be found at **haydudeequine.org**. Now that we've gotten the boring human stuff out of the way… **HI! I’M VAQUERO!** 🐶 I may weigh only 7 pounds, but I have apparently decided that I need to fill every available inch of your heart, your lap, and possibly your home. I am a **Rat Terrier mix puppy**, which means I come with an impressive combination of adorable, playful, curious, and just the right amount of *“What’s that?! I MUST INVESTIGATE!”* 😂 I love wrestling with my brothers, chasing toys, exploring everything I can possibly find, and generally making sure nobody in the house gets too comfortable. I believe puppies should be busy. There are toys to chase! Things to sniff! Brothers to tackle! But after all that important puppy business, I am very happy to clock out and report for **snuggle duty**. ❤️ Give me a warm lap and a cozy spot, and I will happily curl up in your arms for a nap. I am basically a tiny adventure buddy who comes with a built-in cuddle setting. I'm also doing **really well with my potty training** and am eager to keep learning. I'm a smart little guy, and with a family willing to keep teaching me, I'm going to make an excellent companion. I get along wonderfully with **dogs of all sizes** and do well with **cats**, too. I love people, I love adventures, I love playtime, and I REALLY love being loved. So whether you're looking for a hiking buddy, a playmate, a couch potato, a professional snuggler, or someone who will make you laugh approximately 47 times a day… **Vaquero has submitted his application for the position.** 🐾 I'm small right now, but I've got a **BIG personality and an even bigger heart**. All I need now is a forever family to grow up with. **Come meet me. I have a feeling we're going to be best friends.** ❤️
