My 8 months old chihuahua entered her first heat cycle a week ago. I haven't seen any bleeding, but her vulva and teats have been swollen. Yesterday, I started to notice some pale yellow discharge. I read that this occurs during the second stage of the heat cycle so I'm surprised there was no noticeable blood discharge first (apart from possibly one tiny little spot on the bed covers, but then again I also read that it can go unnoticed in some dogs?).
Anyway, her belly has also been slightly bloated for 2-3 days and this morning she has vomited 4 times (pale yellow liquid 3 out of 4 times). She doesn't want to eat or drink water. She even refused chicken puppy meat and treats (she was eating normally until this morning btw). She has seemed increasingly unhappy and tired over the last couple of days and right now she seems quite lethargic.
I read that it can make them nauseous, but is it normal for a dog to be this sick during their heat cycle?
Or could it be something unrelated to the heat? Should I be worried?
Thanks in advance!
BTW (before anyone asks me), yes I do intend to have her spayed / I have no intention to breed her. I wanted to have her spayed before, but my vet thought she was too young / too small and advised to wait until after her first heat.
