I hope that everyone is feeling better soon! Maybe you could ask your vet when it would be ok for your two little ones to be around your big dogs again. I'm really not sure how long KC is contagious
I was very lucky that Belle didn't come down with it, as all 3 of mine are always together.
I'm sorry that your adoption didn't work out, and on top of that it made your babies sick! You seem to be very generous and loving, and I can understand why you'd want to rescue another furbaby. Hugs to you and your pups, and I'll pray for a quick recovery and good health for them all!
