JW means the dog has achieved its Junior Warrant,ShCm means its gained its certificate of merit,SH CH means its a SHOW CHAMPION,CH means its a full champion,i.e in the show ring & in the field.IMP SWE means its been imported from SWEDEN,likewise FINLAND.The endorsements are the same as what i put on my pups,I.E i dont want people breeding from a bitch i sell as a pet,nor taking my pups out of the country for resale.You said that the pup is sold as a PET ONLY,which is ok to do.
Hope this helps
