This temperature is a cause for concern-especially afetr a recent surgery! An infection is very possible and if left untreated could be life threatening! Your baby needs to see a vet-there may be an emergency clinic in your area.
i would prefer to see our regular vet, but might not be able to till monday morning. is there anything we can do till then
I would NOT wait until Monday and this baby especially because of her size!! I would have her seen TONIGHT! This could be life threatening-not worth the risk.
i do not feel that this was helpfull.
Unfortunately-from what you are describing-this is not a condition that I can help you with on line. This is also not a condition that can be treated with over the counter medications. I have chihuahuas of my own and know the breed very well. Your situation is concerning-I would rather be safe than sorry. Your baby should be seen at an emergency clinic.The shivering is a sign of discomfort and your baby has a fever-not good.
