When you have a puppy from a young age it is best to touch their ears and feet as much as possible. As dogs grow up some get very weird about their feet and ears and don’t want anyone touching them. That’s why it so important to get them used to being touched and handeled make life easier as they get older.
I sit on the floor and first brush my dogs so they calm down, I brush them head to toe, under their neck, their belly, chest and even their legs and tail. Once I finish brushing them I start messing with their feet and touching their ears.
If your dog has dirty ears and you are not able to touch their ears for the amount of time you need to clean them you can always use an ear wash. I have attached a picture of an ear wash that you could use.
Reasons to touch:
Feet: Cut nails, or if something is in their pads.
Ears: Ear mites, to clean the dirt out of their ears, and god forbid if your puppy gets an ear infection it will help to put ear drops in their ears.
