Have you tried a harness? Maltese have such delicate necks that a harness would be much better. Also if you want to grow out his coat, the collar will mat it.
JMM have any tips?
All I can say is I have just put a collar on Noel (short coat) and left it on. She eventually didn't seem to realize it was there. But if he does put up a fight, then perhaps save a special treat for those times that he wears it. Put it on and treat him, or get out his favorite toy and play with him to distract him from it.
