A very useful info!
I always remember a dog owner that came to our practice with a dead Fox Terrier in his arms.
He left the dog in the car for less than 1 hour… but temperature rises quickly. I still remember this person crying and saying that he was willing to give ALL his money to bring the dog back to life. A very sad situation…
As you can read in this post, dogs are bad fighters against heat, while they resist fairly well to cool weather.
I like specially the comparison between humans and dogs, that emphasizes why dogs are more likely to developp heat stroke than humans: a main point is that dogs can´t sweat, except trough a small area in their paws.
And please NEVER leave a dog in a car: temperature rises very quickly and dogs thermoregulation is bad (they start panting at 23ºC!, so 60-70ºC inside a car is life-threatening).
When dogs temperature reaches 42ºC, cells start diying, and so the dog does.
It is easy for Brachycephalic dogs to suffer from heat stroke, as their “special” airways not only difficult inspiration but also (this is a recent discovery) expiration, so they do not eliminate heat normally and this contributes to rising temperature.
When trying to help a dog in this situation, a common mistake is trying to lower temperature by putting the dog in a bath: a too quick temperature´s drop is dangerous. I can tell you because I have experienced it. It is better to give intravenous fluids and put moisted towels on the dog.
Dogs like Boxers are athletes: but not during summer at hotter times. I also remember a Boxer that died after spending 2 hours, at lunch-time, running after his owner during a bike tour.
And Pugs and French Bulldogs, you already know, are also very sensible to heat. As well as the worst breather, the English Bulldog. Be extremely cautious with these breeds, particularly during summer.
Hope this helps,
Dog walks are going to be in possible record breaking heat today. 105 Fahrenheit is the forecast. Game Time Dog Services is VERY aware of temperatures because it can put you in a life or death situation. I have covered the basics before, but I found this fantastic one-sheet on The Hydrant that puts it all in one place. This is an IMPORTANT read for the dog owners out there!
