This is really sad to read Callum, I have a Dog and dread the day coming where that decision may have to be made. He is now just coming up to 5.

Your Dog sounds so special, you have obviously had great times with him and you are now there with him in his difficult time now.
You are right,their loyalty to you is never questioned, always pleased to see and hear you and there all the time you want them to be.

Try to be strong Callum and for sure he clearly has a great friend in you as it is clear you think the World of him,as you say too, they become one of the family.
Thinking of you.
