Yes, get her to the vet ASAP. This could be parvo, which is fatal if not treated. Blessings - Blu
I agree with Margot.....My first thought is always PARVO & trust me, it's fatal if you don't HURRY & get her to her Vet! Plus, a death from this virus is something you DO NOT want to see.....Make the call, now....Let us know what you find out & good luck.....Karla
A small puppy can go down quickly. I strongly suggest you get to the Vet ASAP to find the cause and hope it is not Parvo
