I have a Contendro mare whom I bred in Germany. I subsequently retried in Canada with frozen, but no luck (the mare dam was never successful with frozen).
Contessa is a rubber-ball, loves to move, exudes confidence and joy. She passes these qualities to her foals. I have bred her for dressage (5 x Sir Donnerhall, 1 x Romanov) and her foals have had great type, movement and temperament (confident, friendly). Tess is not tall. I agree with all other posters; he does not add height, but produces elastic, correct-moving, athletic foals of great type. She has clean legs, great feet; so do her foals. In addition to having the 2nd highest jumping breed index, Contendro is in the top 5% for dressage. A breeder in our club has used him many times - top foals, talented jumpers (winning young horse classes), Elite Mares, Best Canadian Bred Mare, MPT winner … His are all from frozen.
Yeah, I’m a fan too
