One of my Aso just died and ever since then I've been paranoid that my other dog will die too. Am I crazy?

I'm very sorry for your loss. The loss of a pet isn't an easy loss to handle.

No, you're not crazy. You're grieving.

You're holding onto the other dog tighter because you don't want to lose them too. It's understandable. Enjoy the time you have with this segundo dog and make madami good memories. And revel in the memories you've already made with that first dog. Live life. It's too short not to. Sometimes talking to someone else or finding something you pag-ibig to do to take your mind off of it helps.

What did he/she die from?

No ur not crazy.
But do ur homework. If dog died of pavo the germs stay in the yard. U have to tabing-dagat entire yard to kill germs.
But life goes on. If our freind dies we have a wake. N a memorial. Then we accept what has happened n ilipat on. Such is life. Death is a part of life. Dnt shut up shop. Ur mate wouldnt want it. He would want u to remember the good times n all. What did he teach u. But keep his/her memory alive. They r always alive in ur heart. Pat another dog n say their name. Thru the kingdom of heaven he/she will pass u a msg. But b proud. B happy u wer a strong part of their life. They cheered u up n made u laugh. They may not b human but they r of a kind who respected u.
But soon it will b puuppyy time or u may get a visitor from a stray.
Nothing wrong with being cautious.
Think happy thoughts of them. They will always b alive within you.
Thanks for sharing.
