Bydd creu cyswllt clir rhwng ci â’i berchennog yn helpu i annog perchenogion cŵn i fod yn fwy cyfrifol, ac yn sicrhau lles yr anifail os yw'n crwydro neu'n cael ei anafu. Er bod gan berchnogion cŵn eisoes ddyletswydd gofal yn sgil Deddf Lles Anifeiliaid 2006, mae hi’n gynyddol bwysig sicrhau bod modd cysylltu perchnogion â’u cŵn.  Gall fod yn anodd iawn sicrhau bod y ddyletswydd yn cael ei chyflawni heb ddull o adnabod perchnogion cŵn. Bydd microsglodion yn ffurfioli ymhellach y berthynas rhwng perchennog â’i gi, gan sicrhau bod perchnogion yn fwy atebol am anghenion lles eu hanifeiliaid.
Creating a clear link between a dog and its owner will help to encourage responsible dog ownership and will also ensure the welfare of that animal is not compromised should it stray or be injured.  Whilst dog owners already have a duty of care under the Animal Welfare Act 2006, it is increasingly important to be able to have a method of tracing a pet dog to its owner. Without this it can be very difficult to ensure that duty is being met. Microchipping formalises the relationship between an owner and pet by promoting the owner’s level of accountability for their animals’ welfare needs.
