I have a 35 day old shih Tzu. He's diet is comparatively of wet food like curd-rice, milk and boiled egg. He's stool is slightly yellowish and loose. I got him home 2 days back. Is it advisable to give him liv52 syrup now once a day? Am also starting puppy pedigree once a meal from today.

Hello, Arlo should still be fed some formula in addition to wet or moistened dry puppy food. This could be in addition to the rice and boiled egg. I would substitute the mild for formula. The liv.52 syrup is no necessary if you are feeding him a balanced diet. The stools may continue to be soft and yellow if the diet is not consistent, if he has any parasites (as he is still too young to be dewormed) or if the meal is hard to digest (too much fat or fiber). Try adding some puppy food and formula for two weeks and see how he responds. Best of luck and hope this helps.

    Hi there. Tobi's stools are not normal, it appears that he isn't digesting his food well, hence the color and loose nature of the stool. You can start trying to supplement his diet with some canned puppy food. This will help balance things. I'd also make sure he's been dewormed because parasites can cause issues. Ideally, Tobi should be seen by a vet to make sure nothing else is going on as well. I hope that helps. Thanks for using Petco Pet Education Center, formerly Petcoach.
