Because I have only had one litter prior to the litter that we now have, most of the information that I have on Goldendoodle coats has came from research on the internet. From what I have read, Goldendoodles have a single coat that sheds lightly. There are two coat types, one being shaggy & wavy, and the other being shaggy & wavy with loose curls. A Goldendoodle puppy will have 10-15 coat changes from birth to one year of age, so it is hard to tell what your puppies coat will look like when it is grown. I have followed Molly's first litter from last year, and tried to get a good idea of what to expect from her current litter. Most of Molly's puppies from last year now have long and wavy coats. There was a test on the internet to check for how much a Doodle sheds, and at 6 months of age I ask puppy owners to check how much their puppy was shedding according to the test. The results of that test ranged from no shedding to moderate shedding, and can be seen on the past litter page. Some of Molly's last litter has had their coats clipped, but others are bathed and brushed at home and have not had a professional grooming. I did have one family check to see if they should clip their puppies coat for the summer, so I asked the other families what they were doing. Some were clipping hair for the summer to keep their puppy more comfortable, and others were not. I then called Bogie's groomer to get her opinion. She said that dogs are cooled through their noses and the pads of their feet. If you keep the hair around their nose and between their feet pads clipped she said that they should be fine without clipping coats. She also recommended brushing their coats regularly to get any dead hair out. From what I have seen from the past litter, grooming is needed (it is with any dog), but professional grooming should be a matter of choice.
