Nirdosh, I'll be very honest with you. Ive fed both,the result was following- loose and dark stools, frequent bowel movement and very smelly stools. Pro version was not meant for the puppy. I then started feeding canobites and the result was great- ideal weight as per the breed standards, no more loose, dark and very stinking stools. I know results can vary from one dog to another but then ive been following dog spot for very long now and seldom have i come across positive feedback about pedigree from anyone. Would request to read my above post and give valuable inputes.
