Yes you can get a labby look and have a wavy coat just check the body structure, stay away from the longer legs, look at the head and if it is blocky or not and if the body is slender or more hefty looking, then look at the coat you can usually tell about 5 to 6 weeks so if they allocate before then it will be hard for you to tell, a lot of the bigger breeders won't allocate until 5 to 6 weeks. Hopw this helps.
