All Countries - PLN-Associated Variant Genes Test:
No matter the result of your dog’s DNA test, health testing, at least annually is still advised.
If your dog’s results are Heterozygous (i.e. having 1 copy of the variant alleles), in addition to regular blood and urine screening tests, beginning at age 2-4 years a UPC (or MA if in USA), might be checked every 6 months. If abnormalities are found, further testing is warranted.
If your dog’s results are Homozygous Positive (i.e. having 2 copies of the variant alleles), in addition to regular blood and urine screening tests, beginning at age 2 years a UPC (or MA if in USA), is recommended minimally every 6 months. If abnormalities are found, further testing is warranted.
If you have not had DNA testing done, it is recommended you follow the guidelines for a Homozygous Positive dog. For more information on DNA testing visit the DNA testing page
