Hi....our Lambeau was born Nov 1, 2012. He was a singleton. At his 1st vet visit on 12/29 he weighed 2lbs 5oz....on his 2nd vet visit on 1/26 he weighed 3lbs 3 oz. His next visit is in a week and I can't wait to see what he weighs now. He's been a good night sleeper from day 1 and potty training is going slowly....right now we are working hard on play biting...little stinker has really sharp teeth!! Can't wait for this final series of vaccines so we can get out a bit more. My hubby and I are really enjoying this spunky little dude! I think it will be fun to watch our furbabies grow up here on YT
