Coat changes

An acquaintence is thinking about getting a small breed dog and knowing I have a maltese, asked me about malteses. She said she read somewhere that some malteses go through a "coat change." Personally, I don't recall my Amanda every going through a coat change, or if she did, I didn't realize is.

Can anyone tell me what a coat change is (or how to recognize it), when it occurs and if one should do anything differently as far as care? Is this at the time they go from like puppy hair to an adult coat. I am just baffled by this question. Thanks for any information.

• Some Maltese go through a coat change and other's do not. Those that do this can experience a change for the better OR for the worse. Generally, at the time of sexual maturity (6-8 mo.) we have seen SOME of our Maltese go through a coat change - some have even done it earlier. What happens is that the very texture of the coat, as it is growing, changes. Sometimes you can even see a "line" on the side of the dog as it grows in. There is really nothing you should change as far as grooming is concerned - you must simply be more alert and attentive in case your coat is changing into a texture that needs grooming more often. In our case we generally find a better coat coming in behind what we call the "puppy coat" and we end up trimming off the "ends" (gradually as the coat grows) so the coat has a consistent and healthy look to it.
