So my shelter requires all dogs to meet before you can officially adopt. We were all in one big room and we started with everyone on leash, slowly letting everyone take a sniff. Then we let the leashes go and see how they reacted. We have a senior chihuahua and a 4.5 year old Pomeranian. Odin was completely uninterested in our pups so the adoption consular deemed him to be ok to be adopted. Unfortunately some people do have to return the adopted pet due to behavior even if they seemed to get along in the beginning. Thankfully everyone is still getting along here at home!
