Seizure duration

[Gina7474]

My dog is 9 years old. He started having sudden onset seizures about a year ago. About a month apart. Then for 24 hours he has cluster seizures and then fine again for a month. Very said puliminary tests look good but to go into more detailed testing is much more expensive so we couldn't afford it but he was fine otherwise so just once a month we would make him comfortable for the day, allow the seizures to pass and continued on with life. This past episode has been so much worse. The seizures started 4am yesterday morning so we did the usual to prepare him for what was to come for the day however by 12 30 am the next morning he was still having seizures getting increasingly more intense. The vet again said all he could do was suggest was more testing we unfortunately still can't afford.so all we could do was keep him comfortable at home. By 1am the last seizure hadn't passed. Now 12 hours later he hasn't recovered. His exact movements for 12 hours have been lying there 20 minutes wobbling to a new spot, collapsing for another 20 then repeat with absolutely no change. He isn't aware of anything around him and responds to nothing or no one. We are now deciding on euthinization. Is it time to let him go. I'm feeling if he still hasn't recovered he isn't going to. This is heart wrenching. The only answer the vet has is he can't advise without further testing we still can't afford. Just deciding what to do here. He's still the same. Please don't judge me ok. Things blindsided us in life we aren't prepared for so please no nasty comments about taking care of my dog. I am doing everything I can possibly do. Thanks in advance
