Another common cause of aggression caused by manipulation is a minor personal experience. Nail trim and bathing are the two most common causes. When cutting dog's nails, easy to "speed up", i.e., cut the blood vessels that enter inside the nail. Painful for the dog, a sure way to cause a permanent dislike for nail scissors. Washing is something many dogs find difficult to negotiate. Many landlords, when they meet an angry or half angry dog, have it complete washing them to restrain by force.
This only increases the sense of panic in the dog. It enhances influence as washing something that should avoid at any costs. Defend against him with a display of teeth and hair at the end. Can I "train" on it to enjoy rigor and stability? In a word: Yes. Much easier to start from a young age. Treat with much of gruff and make him familiar with touching it and rubbing. Young dogs enjoy being treated; only older people who have had little physical contact throughout their lives sometimes discover physical affection is difficult to accept.
Practice lifting your legs and touching them with scissors. Practice taking them to the bathtub (or outside, under the tap - whatever serves you. But lukewarm water is more fun for the dog than an icy stream!). Increase the treat with much of praise and a small gift sometimes.
For an older dog who may have many unpleasant driving/grooming experiences, things get harder. You must undo the damage earlier caused by those awful experiences. What you can do by taking things slow, focusing on keeping your dog calm. The moment you show signs of stress, stop and allow yourself to relax. Try to turn everything into a game: Give it much of compliments, buds, and desserts. Take things slow. Do not press too much: If you get stressed, stop.
Dogs show aggression: they warn you to retreat, otherwise! If you think your dog does not accept to be a professional, no matter how much practice you do. Best to shift the job to professionals. Your veterinarian will cut dog nails. (be sure to tell him first he becomes aggressive when a clippers nail out, so your veterinarian can take precautions!).
Dog brushing and cleaning, dog work is a booming industry. Just a small fee, you can get a dog washing, trimming, and carving. Everything else that requires experienced professionals. (again, be sure to inform them of your dog's reaction to the first experience!)
