liver disease?

[hoonhoon]

does anyone know what are the symptoms of liver disease on shih tzu?

i dont actually know if there is something wrong w/ my tzu "missy". i brought her to the vet to get her general checkup and what they did was just check the ears for mites, weight, temperature, and "kapa-kapa" sa body ni missy. the vet told that there is nothing wrong with missy. missy's poopoo is on a very good consistency. i think the smell is also normal because the smell of other dogs poo is the same. her leak is normal also(indi naman mapanghi mashado). her eyes are also normal pero the one thing i noticed is yung eyes nya mejo nakaluwa... sabi ng binilhan ko kay missy ganun daw yun since birth pero normal naman. mejo ganun din yun kapatid nun. missy is 6months now. normal naman po yun eyes mismo sabi ng vet. normal po ba sa shih tzu ang ganun eyes? mejo malakas din pala si missy uminom ng water. ang activities nya lang naman per day is run and run and eat and sleep. mga few mins run tapos mya mya antok na. normal po ba to? kasi natatakot din po ako baka indi normal ang paginom nya nag marami e and yun parang nauuhay sha lagi.

missy eats science diet pellets for pups and also canned pedigree (because NB is out of stock). i mix the pellets w/ lukewarm water so that it will be soft and then i mix some bolied chicken or liver. is that ok?
do you prefer to feed dry pellets with chopped boiled chicken/liver?

i also give missy LI-C-VIT multivatimins for pups.. ok po ba to?

are there any vitamins and shampoo that can make missy's coat thick and remain white? and also how much and where can i purchase those?

i would gladly appreciate all your replies...

thanks!
