Then, researchers collated the owner-reported well being info and in contrast the danger of every purebred and hybrid having a number of of the 57 most typical problems present in canine.
Key Findings
General, this examine discovered no important distinction in well being dangers among the many three most typical designer crossbreeds and their purebred mother or father breeds in 86.6% of the well being dysfunction comparisons. For the remaining problems with statistically completely different odds, hybrids had the next danger of seven% of the 57 well being problems researchers analyzed and a decrease danger of 6.4% of problems.
