Use the right product for the setting
A collapsible home crate and a transport kennel may serve different purposes.
Size using manufacturer guidance
The dog needs appropriate space without relying on a generic breed label.
Inspect doors and latches
Damaged hardware can make the crate unreliable.
Crates are not treatment for anxiety
Behaviour problems or distress should be discussed with a veterinarian or qualified behaviour professional.
General product-selection information only. A pet's health, anatomy, mobility, breathing and behaviour can change what equipment is appropriate. Follow product directions and ask a veterinarian or qualified animal-care professional when those issues matter.
