Do not try to get second opinions from the internet. Your pet may be in trouble and what you really need to do is take them to the nearest Vet. I hope you have an emergency center for animals in your city. If you do, give them a call or just take your pet on over there so they can evaluate the situation.I hope everything will turn out for the best for you. Good luck!

I suggest you let your dog to be treated by veterinary.
