• “I’m Millie! I am almost 2 years old! I have endless energy and I love adventures. My favorite things are being outdoors, meeting new people, and convincing everyone that I deserve another treat! 💛🐶🎀“

  — Nichole K.

• “I love to run around and be silly, especially if I can chase a ball! Belly rubs are my favorite.“

  — Meredith H.

• “I was rescued from Mexico and then from a shelter two years ago. I have an adopted sister dog and we just recently moved to Oceansde“

  — Michelle B.

• “Millie loves to play fetch with her tennis ball and any chance she can cool down in the water she’ll take it! Lakes, ponds, baby pools, you name it.“

  — Sarah A.

• “Millie is a very vocal bossy hound mix! She loves to run especially after anything animal or squeaky but doesn’t like to be chased as much. She has a smaller, leaner build and so dog parks make her feel a little more on the defense since she tends to be chased and barked at. She also is pretty protective so a dog coming up to her people… she is not a fan of. She is fine playing with any dogs one on one as long as they don’t mind the bossiness of her! Her recall is hit or miss, if she picked up a scent or animal she’s interested in, everything is in one ear and out the other. She has leash reactivity pretty bad and does not like most people approaching me while on a leash.“

  — McKenzie C.

• “Millie is a black lab, rottweiler, german sheperd, austrailian sheperd and blue healer mix, she love to play with people but is shy at first, can be reactive. Working on training her with other dogs and more people for social skills“

  — Alia K.

• “She was dumped about 6 weeks after having puppies, never lived in a house, had a great "Foster Mom". I adopted her in April 2022. Birthday guess is late in the year 2019.“

  — Laura S.

• “Silly Millie!! This lil girl is absolutely full of life and just happy to be here. She has the goofiest personality and absolutely adores annoying her older brother.“

  — Gia C.

• “Millie was a rescue! She is full of energy and life but gets a little anxious sometimes!“

  — Sam H.

• “Millie is a 2 year old female beagle. She was rescued from Ridglan farms in may. She is still very shy but loves playing and running with other dogs“

  — lindsey m.

• “I’m almost 3. I love other dogs! I go to the dog park once a week for the past 2 years. I’m super social and a little awkward at times. I like to sniff around a lot. And sometimes I’d rather do that than come when mom calls me. I also like to run! Wanna run with me?! I really am a sweet girl.“

  — Kathryn N.

• “Ummm hello, my name is Millie. Anywhere that is not right next ro my owner is scary and unknown and I dont like it. But they are helping me be so brave! I have so much love to give and want to experience the wind in my fur but that leaf moved too fast and now im shaking with fear.“

  — eli j.

• “My name is Millie. I am 2 1/2 years old and have lived with my mom since I was 11 weeks. I am a very sweet girl but have pretty bad anxiety and fear issues so my mom likes to take me places to sniff and run around where I won’t run into anything that scares me.“

  — Kim E.

• “Hi, I’m Millie! 🐾 I’m a super sweet girl who loves exploring, sunbathing, and getting the zoomies. I only have one eye, so my depth perception isn’t always the best, especially when I’m running around. A more open space with minimal objects, obstacles, or things for me to accidentally run into is perfect for me. Give me some grass, sunshine, and plenty of room to zoom and I’m a very happy girl! ☀️🐶“

  — Katie K.

• “Loves to play with other dogs. Working on recall and other tricks. Can be a little shy around new people but will come around. Up to date on all shots“

  — Daisy T.
