Dogs in kennels experience multiple welfare stressors: separation from their owner and home environment, novel surroundings, kennel noise, restricted space, altered routine, and proximity to unfamiliar dogs. Kennel stress syndrome — characterized by reduced food intake, pacing, vocalization, and self-trauma — affects a significant proportion of boarded dogs.
Kennel design profoundly affects welfare. Larger runs (minimum 4m²), solid partitions between kennels to reduce visual and noise stress, sleeping platforms, access to outdoor exercise areas, and visual enrichment (windows, toys) significantly improve welfare outcomes. Noise levels below 85 dB reduce stress.
National kennel club accreditation schemes (UK Kennel Club, American Boarding Kennels Association) set minimum standards for kennel design, hygiene, staffing, and animal care. Third-party inspection ensures compliance. Higher-tier accreditation programs incorporate behavioral welfare assessments.
Cats are often more stressed by boarding than dogs due to their strong territorial attachment. Individual chalets (rather than communal cattery sections) significantly reduce fear. Hiding spaces, elevated perches, and familiar-smelling items from home reduce cortisol in boarding cats.
Pre-boarding assessment of individual animals — health status, behavioral history, anxiety indicators — allows facilities to tailor care. Animals with known anxiety disorders benefit from additional support: familiar items, pheromone diffusers (Adaptil for dogs, Feliway for cats), and extra handling time.
Home boarding — where animals stay in a private home — provides a lower-stress alternative for dogs that cope poorly with kennels. Regulation of home boarders (local authority licensing in the UK since 2018) ensures minimum welfare standards. Matching dogs to appropriate home boarders requires good information exchange about the dog's needs.
