If there's anyone here who lost a pet who might have any advice they want to give me about grieving and overcoming loss, I'd really appreciate it. My dog who I've had for 4 years, he was 6 years old when we got him, passed away yesterday morning after suffering from a seizure. He had seizures on and off for the past few months, but he hadn't had any for weeks until a couple days ago when he had a small one and he wouldn't get out of bed. He wasn't eating or drinking. Yesterday he started having a seizure but my sister noticed his tongue was blue and for the most part when he'd seize he'd scream, this time it sounded like he was choking or something that's when he closed his mouth and let out his last breath. My brother, sister and mother were with him when he passed. I was home, but not in the room. Now he's gone and I'm kind of finding it hard with coping. He was such a good boy.
