How do you groom a shaved poodle?

It sounds like the cut she has is a basic puppy cut which is probably the most common cut in just pet poodle. Mine have alway had that cut more practicely that the fancy show cuts. Poodles need a trim about every 6 weeks but you should brush daily especailly the ears if the fur is left long. A slicker brush is great for them but you need to be gentle and older poodles the coat does tend to get thinner so a bristle brush is good for the main body if keep short. Poodle ear also need regular plucking as they have hair in them you can ask you groomer to do that. They are prone to ear problems so you need to keep an eye on there ears that they are clean and don't smell .Poodles are great dogs who love to love and be loved they love to please there own. In the winter they do feel the cold so need a nice warm coat. It is great your gran has adopted this little dog and give it a second chance of love she won't regret it. They are super dogs.
