Please don't give your puppy any more of the over the counter dewormers. Some can do more harm than good. When you take her to see the vet tomorrow, bring in a fresh stool sample with you so it can be tested. Her sneezing may be kennel cough. It's usually not serious unless secondary infection sets in...all the more reason to have her seen by a vet asap.
Please check back with us to let us know how she's doing.
