Our 9.5 month lab is on day 5 of her season. She’s been pretty lethargic since it started - still playing in short bursts in the garden but usually she has boundless energy. For the last 24 hours she’s been offer her food, had a couple of bouts of diarrhoea and one vomit (which ate back up as usual). Still weeping, still wagging her tail, not dehydrated. I’ve no experience of bitches on heat - is this illness on top of her season or just her being on heat please?
