Spring care: grooming time

Step by step, my dogs take on the appearance of pets. I try to do everything so that they do not look and feel like dogs from a shelter. Of course, there are many of them, and each of them would like to be the only beloved dog. But I do the maximum that I can do for them.
So, having taken a bath, Athos is completely dry and now I clean his ears and comb the fur with a furminator.
Some of them also need new collars. The collar must be with the address.
