Well my puppy went to the vet this weekend and they found he had roundworm.He was wormed 4 weeks 6 weeks 8weeks and now 13 weeks. Also by the way I just changed my puppys food this weekend to Natural Choice large breed puppy he was on purina and he was never holding it down he was throwing up every other day he was not chewing any of the food it appeared. He was playing after he was wormed about 10 hours later and he just vomits up what appears to be black rock tar looking stuff and he just went about his way. Well this morning after eating about 3 hours later he vomits up a little of his puppy food not as much as before it looked like completely digested mush. He is vomitting every other day it seems. He acts completely healthy though other then vomitting every once and awhile.. My mom thinks it because he plays right after he eats, but Im getting concerned about it because I have NEVER seen black vomit before in my life.I try to get him to relax and settle down after eating,but he just goes into a hypermode sometimes and if you crate him while your in the room he will yelp and whine and scratch the bottom of the cage or slam the sides of the cage like a wild monkey.lol.Sho uld I have him checked for something else because he does appear to look thinner then my other saint did at 13 weeks old, but she also had heavier set parents too.She weighed 39pds at his age and he weighs 33. I was thinking that may be a bit on the small side for a male. Im just worried about his health and making sure he is actually get food in between the throwing up every once in awhile. My vet said roundworms will make them throw up alot is this true as well? I have had puppies before that had roundworm and never threw up.
 Also I have seen alot of people talking about cherry eye, but what are the signs of cherry eye? My 5 month old Saint has really droopy eyes nothing appears to be hanging out except for eyes droop alot and you can see the pink underneath them and shealways has eye boogers its the color like white snot well Im sure eye boogers is not what its professionally called, but I was wondering is this a sign of cherry eye or soon to be cherry eye? I know our air tends to be dry in our house and was wondering if this could be a factor for the dogs eyes as well I know it bothers mine severally, but cant seem to find anything to help with the dryness.
  Hopefully someone can help me out here I'm new to X-large breed dogs these are my first 2 ever and I seem to panic alot over them and probley am driving my vet nuts by calling the tech every other day and asking questions.I just want to make sure there healthy and happy.
