my 6 month old puppy is normally very playfull and loves to run around, however she recently got really ill she vomits saliava,hasn't eaten anything, she drinks water,but vomits it out,she is lethargyc has no energy and she doesnt seem to be improving I've only notice her poop once and it was watery with blood and a couple of worms.I have no idea whats wrong with her or how this might have happen it just seem to happen overnight.She has been like this for the past 3 days I haven't taken her to the vet because I cant afford to take her.I will take her to the vet as soon as I can.Everytime I see her I breakdown and cry I think she may have worms,but I'm not sure please if anyone has an idea of whats wrong with her please help me!thank you
