"Spot-bot" or "Rocky Cool Hall"

This little friend was barking on our front porch at 12:30am Saturday morning. We tried to find his owners, but it appears he has been passed around the neighborhood for almost a month. A neighbor who previously had him took him to vet and he is negative for heartworm and kennel cough.  The vet also said he is around 10 years old based on his teeth.  Of course we want to to find him a permanent home as we cannot keep him because we already Baylor.  Caelin has named him "Rocky Cool Hall" and Cade named him "Spot-bot".  I hope we are not adding to his confusion, ha!  He is very sweet, appears potty trained, not hyper for a chihuahua, and loves to snuggle with the kids. Other than the occasional barking for potty or wanting love...he really is a sweet dog.  Some volunteers at the shelter we were working at helped give us some food, so now all he needs is a good home.  Caelin especially has taken a love to him and he has been sleeping in her room each night.  The kids love him, but him and Baylor just do not get along.  Baylor annoys him and also scares him a bit.  He will growl at Baylor and did nip at his neck this morning.  In order to try and feed either dog or keep them separated, one has to be kenneled at all times. That of course is not what I want for either of them.  I posted on FB and have some great family leads that may want him...so we are praying it works out.  He has been so much fun since we have had him, he is just not a good fit for our family with Baylor already.  Pray for "Spot-bot" or "Rocky Cool Hall" to find a good home!
