How much is that doodle in the window? Exploring motivations and behaviours of UK owners acquiring designer crossbreed dogs (2019-2020)

Table 10 Multivariable logistic regression modelling of other dogs that were seen at the seller’s premises on the day of purchase of the puppy (n = 5904) with comparisons between designer crossbred puppy owners (n = 1478) and purebred puppy owners (n = 4426) in the UK. Significant associations (p < 0.05) are emboldened. ^aFootnote

Other dogs and their relationship to the purchased puppy (n = 5904)	Designer crossbred % (n = 1478)	Purebred % (n = 4426)	Odds Ratio	95% CI^b	p value
Their mother (dam)	73.1	79.8	0.82	0.70-0.95	0.009
Their littermates	67.7	78.1	0.63	0.55-0.73	< 0.001
Another dog(s) they were not related to (e.g., another breed)	35.8	28.6	0.97	0.83-1.12	0.649
Their father (sire)	21.5	24.8	0.51	0.81-1.11	0.949
I only saw my/our puppy	13.7	9.51	1.21	0.99-1.49	0.062
Adult dog(s) they were related to (e.g., aunts, grandparents, older siblings)	3.00	7.41	0.43	0.30-0.61	< 0.001
Other puppies (unsure if they were littermates)	4.19	2.96	1.41	1.00-1.99	0.047

^aFixed covariables used in this model were owner age, UK region, acquisition year (2019 or 2020), whether children were present in the household and whether the owner had prior dog ownership experience
