Happypet’s grass seed pack supplies 30g untreated, pure ryegrass seeds (as used by BioGro and Certenz organic producers) plus growing instructions.
In dogs, eating grass seems to have a social component because others in a group will start eating grass if one dog does.
Dogs enjoy being hand-fed grass by their owner (hold on to it so they can run it through their teeth).
Old dogs with missing teeth especially appreciate being hand-fed long grass.
Happypet grass can be grown in a pot or in a special area of your garden.
