How to prevent hip dysplasia?

The main option is to get a healthy puppy from parents whoose hip condition is written in the pedigree.
· Food spectre has to be wide and balanced, without too high energy and protein value, balanced natrium, calcium, calium and phosphore ratio. More expensive the food – bigger probability of quality and ingredient balance – lower the risk of hip dysplasia
· Too large amounts of food cause hips be overweighted and bent
· Puppy has to moove around only a limited amount of time, mostly on flat surfaces with no burden. Prior to one year of age it mustn't run with a bike or jump over obstacles. The advisable amount of activity is 1 minute of walk a day for each week of age ( dog is 14 weeks old – it walks no longer than 15 mins a day )
· Puppy must not jump or rise on rear legs. It is highly advisable not to walk on stairs – carry the dog for the first 5 months of age
· Puppy must not walk on smooth and slippery surfaces : falling may cause scretching and weakening of the linking tissue and airness in joints
· Jumping over obstacles or from a height should be prevented untill one year of age
· The puppy should be prevented from playing with an adult dog : it could harm it, so scretching same as on slippery surfaces may occur ; but even more serious injuries may happen which cause later negative consequences in relations to other dogs! While picking up the puppy, the right hand has to support front legs, while the left hand carries it's body weight
