The welfare of companion animals during boarding and kennelling depends on facility quality, staff training, and the individual animal's ability to adapt to unfamiliar environments.
Kennelling and boarding welfare varies enormously between facilities, with the gap between excellent and poor provision creating very different experiences for the animals involved. Dogs in high-quality kennels with good socialisation, enrichment, regular exercise, and experienced staff can adapt well and show minimal signs of stress after an initial settling period. Dogs in poorly resourced facilities may show chronic stress responses including reduced food intake, stereotypic pacing, excessive vocalisation, and immune suppression. Cats are particularly sensitive: their territorial nature means displacement to an unfamiliar environment with unfamiliar smells is inherently stressful regardless of kennel quality, and the chronic stress of extended boarding can trigger feline idiopathic cystitis, upper respiratory disease, and food refusal. Home boarding or pet-sitting arrangements that allow animals to remain in their home environment reduce this stress substantially. The 2018 licensing regulations introduced minimum space, enrichment, and staffing standards but do not mandate the higher levels of provision that genuinely high-welfare facilities achieve.
