A Saint Bernard's grooming demand is rated a moderate 3 out of 5, which is accurate as an average across the year and misleading as a description of April. Whether the dog carries the short or the long variety of the breed's double coat, the seasonal shed is a large, concentrated event, and there is a great deal of dog to shed from.
Milwaukee's climate sharpens that. The lake-cooled spring compresses the transition, and the same weeks that bring the first warm days bring the undercoat out in quantity. Households discover the difference between owning a shedding dog and owning a hundred and fifty pounds of shedding dog somewhere in that fortnight.
The answer is a schedule rather than a panic. Two or three thorough professional deshedding appointments booked across the spring, plus a proper undercoat rake used at home once or twice a week through the season, turns an overwhelming event into an ordinary one. Groomers in this market price below the national average, and a giant is always at the top of the size tariff, so booking ahead of the rush rather than during it is worth real money.
