Vets often don't recommend heavily brachycephalic (flat-faced) breeds like French Bulldogs, Pugs, and Bulldogs due to severe breathing issues (BOAS), overheating, and high anesthetic risks, plus breeds with high energy/drive like Belgian Malinois or German Shepherds for unprepared owners, and those with extreme genetic issues like Dachshunds (back problems) or certain "designer" mixes with concentrated problems. Breeds known for temperamental unpredictability, such as Chow Chows, are also flagged by professionals.

Other giant breeds like Irish Wolfhounds, Bernese Mountain Dogs, and Saint Bernards also face significant health challenges, including cancer and heart disease, often earning them similar sentiments from owners.
A red flag dog behavior signals deep fear, stress, or potential aggression, going beyond normal misbehavior, and includes intense growling/snapping without cause, sudden aggression in a calm dog, persistent hiding, resource guarding (food aggression), freezing, destructive behavior linked to separation anxiety, or signs of extreme anxiety like trembling, lip-licking, and tail-tucking, indicating underlying problems needing professional intervention.

The seven second rule. Put the back of your hand on the pavement. If you cannot hold it for seven seconds, it is too hot to walk for your dogs. This rule also applies to dogs riding in the bed of a pickup truck.
