What did studies of Enriched diet find?
3Studies of Enriched diet measured 3 outcomes; the most studied are behavioural and cognitive factors (1 study), shoulder joint mobility (1) and minimum telomere length (1).

Behavioural and cognitive factors

Enriched diet showed no clear effect on behavioural and cognitive factors in dogs after one year of dietary treatment versus control diet.

Enriched diet improves shoulder joint mobility in dogs (on the side with higher vertical ground reaction force, versus control diet).

Enriched diet increases minimum telomere length in dogs (versus control diet).
