OK, I have a question, does anyone know a good worm medicine for my puppy? He's 6 weeks old. I gave him a capsule last night with cheese but he also vomited about 30 mins after and then he went outside and used the potty and had big long worms in it. So just asking if anyone out there may know what I can do. I just don't want to hurt him or over dose him. So reply back if u can help thanks everyone.
