On the subject of dogs - I dont agree with muzzling them in their own garden, it actually does seem unfair on the dog. I'm a bit unsure on aggressive dogs - I dont think you can say that as a dog has gone for a cat, it will go for a child, i do believe they see them completely differently - my neighbours aggressive dog only went for adults, and mainly if they had fluorescent jackets on, he could be trusted with everything else.
As for bringing them home etc - the first two of mine were brought home, one is buried on the street she lived most of her life on, I think the neighbour bought a special plant to go over her grave, and Tig is buried in my 'mud patch (we dont have true gardens, so nothing else has been able to come home with me) - a neighbour offered to knock it down for me a couple of weeks ago, and had to say no cos of her. As Ginger went suddenly, he was taken to my parents allotments, as that is the area he spent most of his life. I can't get my head round cremation and having ashes back (although that happened with teh foster who died, he is in the CP's rememberance garden), so I leave mine at the vets.
