This is a large, immensely powerful worker with a coarse black coat, and the smallest kennel is not an option. The coat bill is the second thing to plan for.
First Class for a dog this size
At 80 to 130 pounds and up to 30 inches at the shoulder, a Black Russian Terrier fits First Class, 6x8 ft, about 48 square feet inside plus 72 outside, which the kennel guide gives to extra large dogs. That is $72 a night for one dog, and $65 from 14 nights. The AKC says the breed is bred to guard and protect and is naturally aloof with strangers, so say so on the boarding agreement.
A tousled double coat
The AKC describes a thick, soft undercoat under a coarse outer coat that needs a thorough brushing once or twice a week to prevent mats, with the beard and mustache trimmed with scissors. On the kennel's bath chart that is the double-coated column: $75 for 76 to 100 pounds and $85 over 100, effective January 1, 2024. Please ask to confirm. A dog this size is a bigger job to wash and dry, so ask for the bath when you book.
The heat is the issue
That same thick coat is warm. The NOAA Vacaville normals record about 100 days a year at 90 degrees or more, so the air-conditioned inside run matters for a black-coated dog. Bring your dog in on a cool morning if you can.
At least 30 to 40 minutes a day
The AKC says the BRT needs at least 30 or 40 minutes of exercise daily and says a BRT needs that outlet to stay content. Walks are included, and the large fenced play areas and the grass field give a heavy dog room to move. The runs are heated in winter, and a coat built for the Siberian steppes will not mind the cold.
Rates in plain numbers
A second dog from your home sharing the run is $61 a night, and from 14 nights the rate drops to $65. The balance is due at pick-up, and check-out is by 11:30 AM.
For 7 nights, one Black Russian Terrier in First Class (6x8 ft) is 7 x $72 = $504 on the 2026 rates. Military families pay that same reduced rate, about 10 percent off; the sheet does not list the two as combining, so call 707-678-6600 to confirm.
