Breed health
concerns may include cataracts, glaucoma, distichia, retinal dysplasia, hyaloid artery remnant disorder, hydrocephalus, open fontanelles,
umbilical hernias, ear infections, mitral valve disease, congestive heart failure, patellar luxation, patent ductus arteriosus, vertebral disc disease and «hanging tongue.»
A small
umbilical hernia isn't anything to be immediately
concerned about but should be corrected with time; if there have been no other
umbilical hernias reported being bred from the dam or sire then it is possible that is isn't hereditary but I can not say with certainty.
