I have a five month old lamb that I’ve noticed is rather foamy at the mouth when he’s chewing. None of the others are. I’ve seen him eating and bringing up cud and chewing. Could it be the extra warm, muggy weather we’re having? I have seen lambs proper dribbling saliva out of their mouths before but seemingly with no ill effects. This one seems a bit lethargic, but again they all seem a bit done in with the heat. The froth is a greeny colour, with extremely small pieces of grass in it. Prob what I’d expect it to look like after regurgitation. He’s not laid on his side, or grinding his teeth and he’s breathing is okay. I first noticed it on checking them last night.
