Hello! Firstly, what colour are the parents? Can advise from there

They are both blue

Take a look at this link. This is one of the most common issues related to Blues:-

There in may lie your problems. I don't know a single decent breeder that would breed blue on blue due to CDA. It's pretty irresponsible. The link Ian has provided will offer more info - in rescue we have seen skin problems such as balding, itching and allergies. Many people sadly give these pups up when they lose their hair and don't look the way they wanted to. I'd talk to your breeder.
