Story
Meet Octavia also called Tavi. Octavia is a big girl with an even bigger heart. Since being rescued from the shelter, she’s proven herself to be the perfect houseguest—gentle, loving, and so grateful for a second chance. Affectionately known as Tavi, she’s ready to leave her past behind and find a forever home where she can truly shine. She just needs someone to give her that chance… and we know she’ll give a lifetime of love in return. Due to Tavi's neglect, she had a severe eye infection when we rescued her from the shelter on the euth list.  Unfortunately, we were unable to save her eye but that doesn't stop her one bit! ##2688495##

Story
Georgie was born in our home five years ago. She is one of the sweetest most affectionate and sensitive animals I've ever had. She does not do well with men that she doesn't know, but once introduced and once she feels like it’s ok for them to be there she is fine. She just needs a little encouragement. She’s not great with other dogs, but that being said I think it just depends on the vibe of the other dog. The biggest problem with Georgie is she has an obsession with cats and should not be in a home with them. She is a very special and sweet dog she just needs the right surroundings.
