Oh dear. Well, it's not the end of the world if you just have to stop Cosequin for a bit, it may only be a few days.
Suggestions - her tummy must be nauseous. I'd clear it w/ your vet to give Pepto - or, ask for Sucralfate (sp?) to soothe the tummy. It's important to get her some carbs quick as this will give energy, stim. appetite, and will help absorb tummy juices. I always keep canned/sliced white potatoes on hand - micro them, mash, bit of butter/salt - and just give straight (no protein) - you can feed just potatoes for a good few days, if she'll eat them. You can also give her some bread or crackers to try get some carbs in there too.
Adding/sprinkling Parmesan cheese can also help, as it's nice and pungent.
Dogs take at least 10 days to get "out of balance" nutritionally - so at this point, just feed her what she'll eat until her appetite improves.
Also, have you tried sweetening her water w/ honey or karo?
Hang in there, dear, you'll get through this and we're all here for you!
