Pa asesiad mae Llywodraeth Cymru wedi ei wneud o effaith gwahardd coleri hyfforddi electronig ar nifer y defaid sy'n cael eu lladd gan gŵn bob blwyddyn?
In 2015, the Welsh Government commissioned an independent review of evidence in relation to the welfare implications for dogs and cats arising from the use of electric collars. The review considered the potential benefits and efficacy of electric collars against animal welfare concerns in order to reach conclusions about whether the benefits outweighed the animal welfare costs. The review is available on the Welsh Government website: electronic-collars-in-dogs-and-cats-review-of-welfare-implications.pdf (gov.wales). There are no plans to review the regulations at this time.
