January Jones is "praying" for her dog after it was bitten by a rattlesnake

Sharing a picture of the snake, she wrote on Instagram: "This baby rattler bit my lil Vinny this morning. I caught and released it but praying for my pup who's in the hospital now. (sic)"

Meanwhile, January previously insisted she isn't a "daredevil".

Speaking about her work with international ocean conservation and advocacy organisation, Oceana, she said: "I'm not a daredevil. I like jet skiing. I don't love to scuba dive. I just get a little claustrophobic. When I do trips with Oceana, I usually free dive and hold my breath. [I can't hold my breath] for too long. It would be like a minute, tops."

But the 37-year-old star admitted her son is a lot more courageous and is desperate to go swimming with sharks.

She added: "We read a lot of books about sharks and dinosaurs. He wants to go swimming with sharks with me, but I've told him he has to wait until he's 10. It's a fair age, I think. But he can go on tagging trips on the boat maybe."

However, January doesn't expect Xander to follow in her footsteps by becoming an actor.

She said: "He knows all the names of every dinosaur, and he wants to be a real dinosaur scientist when he grows up. Not a paleontologist, but a scientist for real dinosaurs. So, he's dreaming big."
