I've had seniors in the past but never had this problem before. Up until now I could support a senior Hooligan on my knees when I was raking them but for some reason Ringer doesn't fit. He has a bad back so I wouldn't dare force him up and he collapses after a minute or two. I can groom everything but his rear legs. I take the Hooligans to a groomer who is very good with them, she always uses an assistant to supprt the old guys while she works with them, but I don't think he's capable of doing this very often so I try to space their appointments as far apart as possible.
