Lab Eating his blanket!

[InkyOctopuswithLegs]

My lab has eaten some of his fleece blanket! He's vomited once, 24 hours after. He's had a poo which had some of the blanket in the poo. He's hungry as usual and acting normally. Should I be worried?

How old is he? Doesn’t sound like there’s a blockage.I’d just keep an eye on him.

Thanks. He's 7,
