I completely agree with you. The animal considers the house as its territory; the appearance of a stranger on it can be perceived as a threat, hence the aggressive behavior towards the visiting master. I would suggest you find Calgary dog groomers. It is better to train your dog to go to the salon than to call a specialist home.
Many dog lovers, having learned what dog grooming is, do not tend to visit salons, but prefer to call a specialist to their home. However, this approach is not entirely successful.
This is a very herd breed. It is believed that the Maltese appeared about 2 thousand years ago. They are perfect, but they sometimes have health problems. Brown spots appear on the muzzle, similar to dirt.
This glamorous dog is always given as a gift to royalty, important persons, poets, philosophers and artists. This animal is not for everyone. There is a lot of trouble with him. Think twice.
