We have five old retired horses happily living out their days in the paddock, rugged, fed and cared for as appropriate - BUT we are a business and should they require expensive vet care they will be destroyed. Horses have no concept of death and length of life, only quality of life.
Waikato Valuta you need to make your own decision but don't let anyone make you feel guilty if you cannot go on.
I totally agree... As I said above, everyone has a ceiling limit, dont feel guilty if you have reached yours...
