Samples cover a broad age range (0.58–14 years), both sexes, and multiple breeds. The dataset provides a resource for investigating age-associated CpG variation and epigenetic aging markers in domestic dogs.2026/06/19GSE307447GSM9224322GSM9224289GSM9224288GSM9224321GSM9224320GSM9224287GSM9224286GSM9224285GSM9224284GSM9224360GSM9224283GSM9224282GSM9224329GSM9224328GSM9224327GSM9224326GSM9224325GSM9224324GSM9224323GSM9224281GSM9224280GSM9224311GSM9224355GSM9224278GSM9224310GSM9224277GSM9224354GSM9224353GSM9224352GSM9224351GSM9224350GSM9224319GSM9224318GSM9224317GSM9224316GSM9224359GSM9224315GSM9224314GSM9224358GSM9224313GSM9224357GSM9224279GSM9224356GSM9224312GSM9224309GSM9224300GSM9224344GSM9224343GSM9224342GSM9224341GSM9224340GSM9224308GSM9224307GSM9224306GSM9224305GSM9224349GSM9224348GSM9224304GSM9224303GSM9224347GSM9224302GSM9224346GSM9224345GSM9224301GSM9224333GSM9224299GSM9224332GSM9224331GSM9224298GSM9224297GSM9224330GSM9224296GSM9224295GSM9224294GSM9224293GSM9224339GSM9224338GSM9224337GSM9224336GSM9224335GSM9224334GSM9224292GSM9224291GSM922429028271307447Mus musculus Rattus norvegicus Canis lupus familiaris Homo sapiens
