have you tried taking her to another vet to get a second opinion?
i just lost my dog last monday to liver cancer. she used to be a voracious eater and then stopped eating and was became very picky... she would only eat roasted turkey and just the dark meat. we tried all food imaginable (of course that are safe to dogs). she was loosing weight fast and we don't know if b/c her liver was pressing on her stomach, we even tried feeding her small, frequent meals. she would still throw-up... so the vet gave her zantac to prevent throwing up and reglan to speed up her digestion so she doesn't feel full all the time and would make her eat. towards the end of her life, we didn't want to see her starve herself away and b/c she was still alert and otherwise active and after consulting with 3 vets, we decided to put a feeding tube on her to make sure she is still being fed. i know this sounds drastic but my husband and i decided that unless she is in pain due to the cancer, we will not put her down and we will try to do everything we can as if she was human.
unfortunately, this past monday she passed away. she had a cardiac arrest :(.
get a second opinion and don't give-up trying different things... it is good that you at least have prednisone to use. good luck. i hope you find some good help for your baby :)
Hello & welcome ......
What are you feeding this girl? Name? How long has she eaten it?
There is a recent post on this forum that sounds like your problem.....It's about 10 questions down on this same page....It's titled: "Weak, Lethargic". Original post is dated Oct. 15. Go read that and see what you think....Come back and let me know.....Karla
P.S. Digestive Enzymes make a world of difference with slow digestion...Also, loose stools.....You have had a fecal sample evaluated for parasites, right? Parasites alone can cause the symptoms your describing.......Thanks....
