this control are very strong in GSD. ALL pupps who have kinked tail are pet and have documents " not for breed" and this go from one generation tho others. ( LKD)
example bitch have kinked tail, she are mate with male and in pedigree be inbreed III-IV born 5 pupps. from this 5 one are with broken tail but can move, others are paralised to head, not can move.
Only good this be GSD litter, but WE have and CsW who have broken tail and go to breeding and theys pupps to have this kinked tail. who be later when this dog without control go to breed? we want paralised liters? or problems in vertebral column.
this can saw in 7-8 weeks without problem, first is touch, later make rtg and have this
this genetic broken - kinked tail and this dog are pet, not for breeding.
in all case mas make rtg and when have rtg we can say this is trauma or genetic. yes, can be and trauma, but not when are pupps in 7-8 weeks, and wolfdog have very strong anatomy for broken, and when owner say " oh this is trauma only" i not very want believe in this.
