A stock kit of Genia Neocol Elizabethan collars: two collars in each size from 7.5cm to 30cm, so a clinic, shelter or breeder always has the right size on the shelf. Each collar has Genia's shock-absorbing neoprene outer edge. If you only need one collar for your own pet, buy the single Neocol collar in your size instead.
Part of the Genia e-collar range.
Sizing
The size is the depth of the cone measured from the neck edge outwards. Measure from the base of your pet's neck to the tip of the nose: the collar should reach just past the nose so the animal cannot get its mouth to the wound. If in doubt between two sizes, go longer for wounds on the legs and flanks and shorter for head and neck wounds, where a very deep cone makes eating difficult. Fit it snug enough that you can slide two fingers under the neck edge.
