very old dog 15 has been a bit wobbly on her back legs for ages not on pain and still loves a walk .
we are going on holiday soon and have a sitter staying with her but i keep thinking i should get a once over from the vet before we head off.
DH says she's been like this for ages and very happily mooches around the garden eats well etc and that the vets will definitely find something wrong with her .
what would you do?
