I have heard very bad things about ProHeart (I'm assuming this is what you are using?).. Heartgard is much better.. and I haven't heard about NexGard. I know the most popular and trusted flea/tick preventatives are frontline and k9 advantix. Also, if she is having these symptoms I would not proceed with giving the Nexguard anymore. I also would not trust giving her this medication if it's for dogs that are 5-10 lbs when she is only around 3lbs. This is my opinion but I'm sure others on the group can give more information on this. |
