[Dailydrool] advice needed

[nancy]

hershey  who is 10 years old and a lab was having very loose stool, no 
vomiting......she went to the vet, and he put her on science diet ID, 
after 3 days of chicken and rice......she also got a shot of penicillin, 
reglan, and an Rx for flagyl......she has finished all, and is still 
having loose stool, not as loose as before, and the smelly gas is 
gone.....she has a good appetite and looks healthy.......vet held off 
doing other tests because they were expensive and she looks/acts 
well.......i don't want to get the tests......for the same 
reason........i also don't want to feed science diet (junk 
food).......she had been eating Kirkland kibble with a spoonful of 
Merrick's canned on top ......does anyone have any suggestions?.......i 
just cooked up some rice and will cook some chicken for her......but i'm 
thinking she will need some sort of supplements in addition to 
this........any suggestions?  are their any other dog food/ kibble 
options??.......i am going to petsmart today and will buy something just 
to get her thru the holiday weekend......thanks, all.......nancy, 
hershey and einstein
