Pet's info: Dog | Shih Tzu | Male | 3 months old | 6.34 lbs
My dog's vet gave him cestal plus yesterday and he has trouble pooping today. He was trying hard to poop and crying and following his tail. Is that side effect of medication? Should I be worried?

Hello. If Nero was severely infested with intestinal parasites/worms, it is possible that the dead worms are causing a blockage. You can try feeding him a teaspoon of canned pumpkin with each meal as this can act as a mild laxative. Make sure there is no accumulation of feces at the rectum that can literally plug him up. Sometimes sitting in a warm bath of Epsom salts can help relieve a blockage, too. If he is still having problems passing feces tomorrow, please have him seen by your veterinarian.
