Abu’s owner passed away

Abu survived a war in the middle east and was brought to my mom by a military representative. Abu does have some anxiety of not being fed. He is ok with little dogs but not big ones. He has a great temperament and gets along well with children. He should be an only dog or could be a buddy with a smaller dog. He needs exercise and solid meals. He would be great on hikes and is the best buddy.
Abu wants a forever home with a good stable owner. Unfortunately, my mom passed away after he was with her over 2 years.
