Thank you that's one of the kindest things someone has said to me.iv never seen him swallow his toy without it being a bit more chewed up. He is a jack Russell . His breathing problems started on a Monday and I could tell he was having problems and it seemed to ease a little before the seizures happened on the Saturday while passing the toy. He still liked to play up until the day before seizures happened. Thank you it's hard to lose him
I am so sorry about your loss of dear Tio.
In all illnesses, especially if very weakening, there can come a 'tipping point', at which point things can go downhill, because the body is vitally weakened. With a dog this can happen very fast. And it is typical of a dog to be very stoical and get on with life even when unwell.
Many people whose dogs pass away from an illness, say "He/she was just fine a few days before, ate food, went for a walk....etc"
If he had been struggling with kidney disease, even though apparently doing quite well, it's possible this led to other complications. High blood pressure is often associated with kidney disease. And high blood pressure can lead to many things going wrong.
Swallowing the rope toy probably did not help, but would that have led to seizures?? It would have stressed him, yes. But he did appear to pass it.
My own opinion is the kidney disease may have led to other complications which his body could not take any more.
In my opinion you did the kindest thing to let him go peacefully.
My heart goes out to you as I know how hard it is to let them go. Bless dear Tio in Spirit.
