Good brush routine
A good brush routine is the most important thing when looking after this breed's coat. And it's something both you and your puppy should get used to very early on. Buy a slicker brush and a comb and brush your pup in their down time with a few treats in your hand.
Washing at home
Unless you have a salon grade blow dryer I wouldn't recommend washing a Pomeranian at home. A good brush out will remove the dander and dirt but if you really have to, rise the feet only and leave the rest to a professional groomer.
Professional grooming visits
Most of my clients keep their Pomeranian coats nice and fluffy with a 4-6 week schedule. Speak to your dog groomer (Dog Hub grooming in Raheny) about what will work best for your and your dogs lifestyle.
Teeth
Start checking your dogs teeth from when they're puppies. Depending on what food you feed them, dry or wet or raw, check regularly for signs of any build up on their teeth. Brushing their teeth a few times a week should help to prevent a big build up. And if you're a fan of supplements, I use a product called "Canident" for my dog (Irish Terrier) and it works a treat to keep the tartar at bay!
Flea / Tick / Worm treatments
Make sure you check your pet regularly for ticks and any signs of flea debris. There are many ways of keeping your pet free of any parasites so find a solution (chemical or natural) that works best for you and your pet.
Vet visits
It is advised that you visit your vet once a year for a general health check. Even if your pet seems healthy, they're professional vets for a reason and might spot something you missed.
