Why is my dog collapsing, choking, and turning blue after walks?

Question

So my dog (10-11) has been having severe breathing problems. What usually happens is when we come home from a walk he collapses on the ground and stops breathing-he's wheezinng, gagging, choking, and frothing at the mouth . It's like his throat closes. He usually poops and pees while it's happening. His gums look blue also.The vet said they were seizures, so he has been on phenobarbital for about a week, it has only made him sleepy. He had another fit today, and my mom and I thought he died. thx. Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 50 lbs

So sorry about your dog. Besides it being caused by a seizure disorder, he could have something like laryngeal paralysis, collapsing trachea or be having a syncopal (fainting) episode from a heart problem. You could try to record one so your vet can see exactly what is happening. If the episodes continue and your vet is not able to control them, ask for a referral to a specialist for more testing. It might be a good idea to take a chest x-ray, have an ultrasound of his heart, and/or examination of his throat to look for laryngeal paralysis. Hope he gets better soon!
