Hi, I have a 40 day old beagle pup. He's been having loose stools since 3 days and poops 2-4 times a day. He strains while pooping, I have been feeding him Lactol 3-4 times a day. I gave him 2 spoons of yogurt which i think didn't suit him and started watery stools. Should i be worried?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Harley! He is a young guy and I don't like young puppy's to be sick for that many days. I recommend you have him seen by your Vet today before we get deep in to the weekend. I would stop the yogurt since that seemed to have either worsen things or triggered the diarrhea. Most dogs and cats are actually lactose intolerant and dairy products can commonly trigger diarrhea. I would also consider getting him off the lactol. At 5 weeks he should be weaned and on puppy food. I would start mixing the lactol in to canned puppy food and see if that stars to improve his stool. When you take him to the Vet bring a stool sample to check for intestinal parasites. Good luck!
