Yup looks like cuddle bug just like ours. We just got our baby B a month ago. I posted the forum right below yours his name is Rusty. Is this guy brindle? Did you get him from someone in Texas? My brother also just bought a little girl 2 weeks ago and she had a brindle brother that looked almost identical to yours.
@Radil.Andrew Yes you should register him... that way his health records are tied to his registration number with the American Kennel Club. And also his pedigree information will be recorded. Did his have DNA testing for Fanconi and/or PRA? Did the breeder mark the color box on the litter registration slip?
