Story
Astrid is a very loving girl! Me and my husband adopted her from the Humane Society when she was 2 months old and she is now about 9 months. She will be 1 in June. My husband is in the Military and he has been having surgeries in his knees. It has been really hard to mentally/physically stimulate her through all this considering we have both been busy with his recovery. We are looking for a good home for her to be loved and stimulated that way she needs to be!

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
I am a fun, loving boy who loves to play. My only fault is I do not realize my size. I think I am a lap dog. I am house trained, and good with most other dogs. I would prefer to meet potential companions before going to a new home. ##2427887##
