This link to the Human Society of the United States contains a table detailing the increase in Dalmatian intake at several shelters following the release of 101 Dalmatians. It also contains footnotes citing several articles in various newspapers, from which I gleaned the following quotes:
St. Petersburg Times, Sept. 10, 1997:
" . . . So far this year, [Patti] Dane [of Dalmatian Rescue] has taken in 130 Dalmatians, a number it normally takes about 2 1/2 years to reach. She took in five on Monday alone. And the problem is nationwide:
Shelters in Los Angeles County report an increase in the number of Dalmatians turned in, including one family that brought in a dog and complained it was nothing like the dogs in the movie, according to the county Department of Animal Care and Control.
Throughout the Tampa Bay area, shelter officials said they have seen a jump or at least a steady number of Dalmatians in the nine months since the movie opened. At the Society for the Prevention of Cruelty of Animals of Pinellas County, which has taken in one or two a week for more than a year, several were brought in last week alone. On Tuesday, one remained: an 8-month-old named Spot.
Among the most dramatic increases was at the Humane Society of Tampa Bay. Before the movie came out, said shelter supervisor Debbie Taylor, about four to 10 Dalmatians were brought in a year.
‘Now we’ll see between four and six a month,’ Taylor said. ‘That’s way, way, way too many. It was families that weren’t ready for puppyhood.’
The numbers are just as grim at the Humane Society of North Pinellas. In 1996, 27 Dalmatians were brought in; through August, 34 have been brought in. Most have been adopted . . .
. . . Dane blames the problem on unscrupulous breeders who wanted to seize on the demand created by the movie and who didn’t warn prospective owners about the dogs’ temperament. Dalmatians sell for about $300-$800 apiece."
USA Today, Sept. 8, 1997:
" . . . In Milwaukee, the Wisconsin Humane Society reports a 15% increase in Dalmatians since the movie came out. ‘Many of them are exhibiting physical and behavioral problems when they’re surrendered to the shelter,’ says Victoria Wellens, executive director.
Katherine McGowan says the movie caused the number of Dalmatians brought in to The Humane Society of Missouri in St. Louis to jump 30%.
‘They’re bringing them in at six months (of age) when they’ve outgrown the cute puppy stage,’ she says.
The Humane Society of the Tennessee Valley in Knoxville saw a 23% increase in Dalmatians the first six months of this year. ‘Movie theaters were bringing in litters of Dalmatians and sponsoring drives to win a puppy,’ says Vicky Crosetti, executive director.
In some cases, the dogs are being abandoned because the warning campaign worked too well. ‘We’re getting couples who say they want to place their 3- or 4-year-old Dalmatian because they’re having a baby and they read that Dalmatians are bad with children,’ says Sherree Gerzanics, head of Dalmatian Adoption and Referral Service in Waterford, Mich. ‘But Dalmatians can be wonderful family dogs.’"
