No one is responding 😡

We have two dogs, a 7 lbs dachshund and a 35 lbs pit mutt, and I’ve been trying to find a friend for the both of them! Luci, my mutt, is too big and rough for Juliet. So I’ve been on a search for two dogs one of each size. I found two separate ads for dogs that would be PERFECT. I called and texted and guess what? No reply. The least they could do is say they are no longer available or something! How do they expect them to find homes if they don’t reply to people that are interested???
