What's wrong with my dog?

My dog is very very old. But he hair started doing this. He will just be sitting all normally but out of nowhere he would start like choking then he'll fall on the ground or like collapse..but he doesn't have anything in his mouth idk if it's like a seizure or what he'll do it then get back up like it never happened I just noticed this like a couple of days ago. my questions are what is happening? Is it serious? Is it just cause he's old? Is it a seizure? Will he die? And do I need to take him to the vet? HELP ME I LOVE MY DOG TOO MUCH!!!!!

My advice is take him to the vet. If he falls on the ground like he's choking that is not good. He may have some diseases or infection in his trought and sad to say he might have pain. Take him to the vet as soon as you can or call the vet to see if he needs over the counter drugs or a vet to help him.
