Is there any place i can get a dog cage from

They only give out cages if you are adopting one

Walmart, petsmart

Sometimes they will give out crates, go into the pet resource center and ask

Or you can try these other places : Letgo, Offer Up, thrift stores (Goodwill, Salvation Army, Savers, ect.)

Try to buy on Craigslist. I got mine at Wal-Mart but it cost about $60.

Like for crate training? Most pet stores should have them. Petsmart and PetCo do. I don't know about smaller stores.
