He's in preschool. How can his teachers not be able to handle something like that? You should find a good school with non-lame teachers for him to attend.

LMFAO!!!

acting like an animal is a super common kid thing

My brother does this. We were told it had to do with his ADHD

When I was like 3 I was pretending to be a dog at the doctor's office and barking at people when they would talk to me. My doctor then sat down with me and also pretended to be a dog by mixing in a few barks with his questions which my mom thought was awesome of him

Hahah

Maybe your whole family barks.

Sounds like he's barking mad! Make sure his classmates keep his paws off him, they'll stop sniffing around.

My sister went through a stage at aged 3ish where she meowed and acted like a cat for a week. Mum got worried because she wouldn't talk at all during that week, just meow.

If I were you, I would of barked at the counselor during the phone call
