Les chiens sont particulièrement sensibles aux coups de chaleur. Heureusement pour peu que l'on soit vigilant, le piège peut assez facilement être évité.

Le chien possède très peu de glandes sudoripares. De ce fait, il sue très peu et rencontre donc des difficultés à réguler sa température corporelle. C'est essentiellement le halètement qui lui permet de maintenir une température correcte. Coup de chaleur : les situations à risque Dans un environnement trop chaud, la respiration du chien s'accélère afin d'augmenter les échanges d'air et de maintenir un équilibre. Ce que les vétérinaires qualifient de «coup de chaleur» ou hyperthermie peut survenir lorsque les conditions extérieures influent sur la capacité du chien à réguler sa température. Parmi les situations à risque, on peut citer : La pratique d'un exercice trop important lors de températures extrêmement élevées. Le surpoids et l'âge. L'attente longue dans une voiture lors de la canicule. Un chien exposé au soleil et attaché. Il peut suffire de 30 minutes dans une voiture même si la température ne dépasse pas les 25 degrés pour mener à la mort du chien. Certaines races qu'on appelle les brachycéphales sont plus sensibles à la chaleur comme le bouledogue, le boxer, le carlin… Les précautions à prendre pour éviter les coups de chaleur : Eviter de contraindre votre chien à passer du temps dans des endroits trop chauds : cour en plein soleil ou voiture. Lorsque les températures commencent à être élevées, ne proposez pas à votre chien une activité physique très intense. Evitez les promenades trop longues dans des endroits ensoleillés. Préférez les heures les moins chaudes de la journée pour promener votre chien. Veillez à ce que votre chien ait toujours de l'eau fraîche à sa disposition. Mieux encore, offrez-lui une petite piscine. Sachez qu'il existe des tapis et manteaux rafraîchissants lors de températures extrêmes. www.veterinaire-lespins.tn
