Frequency of positive pathogenic infections in young dogs compared to geriatric dogs

Positive pathogenic cultures (PPC)	Young dogs (<8 years) (n = 25 dogs)	Geriatric dogs (≥8 years) (n = 28 dogs)	Change in positive pathogenic culture frequency in geriatric dogs	P value
Dogs with before‐stent PPC	8/25 (32%)	17/28 (61%)	91% increase in infection frequency	.04*
Dogs with after‐stent PPC	12/25 (48%)	8/28 (29%)	40% reduction in infection frequency	.15
Change in positive culture frequency after stent placement	50% increase in infection frequency	52% reduction in infection frequency
P value	.25	.02*
