I just got home from emergency care, my 4 yr old yorkipoo ava is there. She got sick Saturday, my ex told me she was going in circles and rolling around with her arms and leg straight. HE took her into the vet and they said they thought she may have vertigo due to low blood sugar. I have her now and she was throwing up and not pooping, she also started looking very weak and lethargic , she was hiccuping so i thought but it may have been a small seizure. I tok her to emergency care and they have her now, they said her blood sugar was so low( 25 and its supposed to be 100) they dont know what it is and i am sooo scared. It can be anything, a liver shunt, she ate some gum, she got into something. Please send good thoughts, im scared and whats worse i cant get a hold of her dad, he is camping and has bad phone reception.
