calf breathing

Why is my show calf breathing heavily when hes laying down and not working out? please help me out!! Thank you!!! <cowboy> <cowboy> <cowboy> <rock> ;D

Only when he's laying down? Are you sure there's nothing going on respiratory-wise...does he have any other symptoms that might make you think he has a cold or early stages of anything worse?...depressed, not eating good, runny nose, runny eyes, etc.?

He is eating fine and all that he does have a runny nose but I gave him a shot of LA 300 6 days ago.

LA-300 is a broad spectrum and that makes it great for lots of different ailments. That also means it's not always the BEST thing for certain specific issues. It should do whatever it's gonna do within two or three days, though. I would talk to a vet about the symptoms you're noticing and decide if it needs to be addressed with something stouter designed to target certain respiratory diseases specifically. Naxcel...Nuflor...Excede...

Ok, thank you I would be greatly honored if you did that for me!!
Thanks again,
