This almost certainly not legitimate. It is a scam.

I live in Michigan, and just got a text from this number wanting to buy my puppies for sale. Problem is, I don't have puppies for sale, I am selling an adult male dog. When I pointed that out, the texter said that he or she knew, and to email them all the details. I think I'll pass...

Funny that this person wants your bulldog puppies and my puppies, and now is fine with my adult dog.

If I were you, I wouldn't cash that check they're sending. Just saying

Oh, one more thing. I'm not selling a bulldog, not even close. So either this person desparately wants a dog, any dog, or its a scam. I lean toward the latter.

wut r the risks of trying 2cash the check or money order this person sends? if i take it 2my bank & they cash it, will i be held liable if it bounces a week later?

now i get another text from same person claiming 2b a 'Judy Morgan' from a different # …. this time its a topeka kansas area code …. wth?

So they send you say $1500 plus another $500 for the "puppy transportation fee". You cash the $2000 check, it goes through, so you send the $500 to "Jerry". A week later you'll get a call from the bank saying the $2000 check bounced, and they are removing the $2000 from your bank account. Unfortunately you've already sent the $500 check. So now you're out the $500.

Google the number again, you'll see posts from all sorts of people who have got this text. Cash that check at your own risk.
