Can someone please explain to me how this sweet angel was unwanted & being neglected at a foster home?

6.5mo american foxhound.

I adopted him at 3.5mo from a rescue. He was apparently being bounced around foster homes. He was underweight, so malnourished that he was eating his own shit, had no concept of peeing/pooping outside & would hold it in until he was inside even if I took him for an hour walk, & he had untreated giardia. The rescue was so eager to get rid of him that they didn’t even check my references.

3 months later he’s housebroken, walks nicely, doesn’t eat his own shit since he’s well fed. & he is SMART. his vocabulary has quadrupled. He wakes me up in the middle of almost every night asking me to move my arms so he can snuggle.

So fuck anyone that thought this boy was a problem, something to tolerate & not teach. He is wonderful. I’m so happy I found him.
