I have 5 of my own and one foster at the moment.
Daisy & Ben, bonded for over 3 years live in garage with a 10x4 permanent outdoor run.
Giselle and Jasper, Just bonded and hoping to collect tomorrow, have a 9ft x 4ft shed with 12ft x 4ft permanent aviary.
Nusha, lost her partner Bungle recently and rejected all others (including Japser, hence his new wifey) lives in an 8ft x 4ft dog kennel & run
Dennis, foster bun, gorgeous naughty conti, lives in 8ft x 4ft kennel & run next to Nushka.
Plan is to open up joining walls to Nushka & Dennis with aviary panels and do a slow bond......
if its works they will have a 16ft to share.
ETA I also have a nutty springer spaniel Lucky
