Story
Hazel is a loveable loaf in search of a comfy couch to snuggle on! She`s sure to charm you with her adorable personality and stunning brindle coat. Hazel isn`t a fan of sharing her yummy bones with other animals, so she is required to be the only animal in her next home so she can be spoiled rotten with snacks and affection! At this time, HSBV is also requiring a home either without children or with children over the age of 10.

Story
Meet Leigha Leigha is a sweet, resilient girl who has already come such a long way. Despite the difficult circumstances she came from, she continues to show us what a loving and gentle dog she is. One of Leigha’s most wonderful qualities is her calm and neutral temperament around other dogs. She has been so easygoing and appropriate in her interactions that she has even been used to help with dog temperament testing. She has been good with dogs of all sizes and has shown an ability to calmly meet and coexist with dogs with different personalities and energy levels. Her relaxed approach to other dogs has made her a helpful dog when introducing and evaluating canine interactions. Leigha has also been good with cats during her time in rescue. As with any animal, individual introductions and interactions can vary, but what she has shown so far has been very encouraging. Her easygoing personality may make her a good fit for a variety of homes, including homes with other dogs. She has shown that she can take new situations in stride and settle into different environments. Leigha is steadily gaining weight and making great progress. She loves affection and has a sweet, appreciative personality. After everything she has experienced, it is incredibly rewarding to watch her discover what it feels like to be safe, cared for, and loved. Leigha is heartworm positive and is currently undergoing treatment. She will need to complete her treatment before she can be considered fully cleared, and her rescue team will provide the care, guidance, and follow-up she needs throughout the process. We are looking for an approved home that is comfortable giving Leigha the time and support she needs to finish this process. Temporary Foster Needed Leigha is currently looking for a temporary foster from September 23 through October 5 while her long-term foster is out of town. Her long-term foster will be able to welcome her back on October 5, making this a short-term opportunity to give Leigha a safe and loving place to stay while they are away. Leigha has been through so much, yet she continues to greet people and other animals with an incredibly sweet and easygoing attitude. We can’t wait to see her continue to gain strength, confidence, and weight as she begins this next chapter. ##2845607##

Story
We have had Nala since she was 8weeks old! She is now 5 will be 6 December 22nd! She is a cuddle bug for sure and loves to play! shes very smart and learns quickly. She is kennel trained, house trained and knows basic commands. She loves her paw held. She will literally be your best friend. She needs an active loving family. I have developed an allergy to her fur and while i have been able to manage it pretty well our work situation is also changing within the next few weeks and i dont want her home alone or kenneled for the majority of the day. She deserves better than that. She is up to date on shots and goes to her annual well checks. Shes also been to doggy boarding and does great. Shes great with other dogs big or small and loves kids. she loves anyone that loves her honestly.She is not spayed but probably should be.She will come with all of her things to her new home.
