An adolescent Hav blowing coat can be a nightmare and impossible for someone who isn't 100% sure of how to keep it in shape.
Leo is 4 almost 5 months old and currently is bathed 2xper week and combed 2-3 times per day. I use a Biogroom Finishing Spray on him when combing. I hope to be able to keep him long and not have to get him cut down during the time he goes through a coat change. Any suggestions for handling the daily grooming when the coat change is taking place? How will I know that the coat change has started? Will the coat mat all of a sudden or will there be any changes in the coat that will let me know when the coat change is starting. Leo is very well-behaved for grooming so I just have to work with the coat not struggle with him squirming about.
I've posted several videos in the grooming section for brushing and combing, but I've found another one, on a shih tzu, there just aren't any proper Havanese grooming videos on youtube that I've come across yet. For me, the only way I could tell there was a coat change was that the coat was starting to mat up. Part of it I'm sure was that it was winter, and winters can be not nice to long coats. There was a lot of static, dry hair, snow, dirt, sand, etc. To get through an adolescent coat change it's important to really nail down line brushing, both with a brush and a metal comb. Ideally you can lay your dog down on its side and work on the coat that way, always paying close attention to the hard to reach areas like the tuck up/loin, the inside of the back legs, the butt and inner butt/leg/curved area, right above the paw pads, the hocks, the belly, chest and inner upper legs, also the armpit. The degree of difficulty will depend of the type of hair your dog has. Mine has a light, yet cottony undercoat, so that was a challenge. Typically the more "fluffy" and active your dog is, the harder the blowing coat phase will be.
This video is kind of long, I actually didn't watch all of it, but she does a quick line brushing so at least you can see the technique. For blowing coat, you would also use a comb, take a little longer and be a little more thorough, use a conditioning mist, and pay extra attention to the trouble areas.
