Fiona About that time of year, it could be 90 degrees and usually rather humid.
I am always anxious about flying these dogs, and think you would be taking a huge risk to put him in the crate.
I am concerned about the heat and humidity as they are mostly inside dogs. Any brachycephalic dog (like a Pug or a Boston Terrier or other flat-faced dog) is at very high risk of overheating and going into respiratory arrest in a situation like what you are describing.
In terms of the issue about the cage in the back of the truck, I would want to know:- how hot is it there? The cage is a hard shell fully covered with many large vents on both sides, so there would be no direct sun on top of their bodies, but on top of the cage itself.
The first is partial sedation which describes a calm drowsy state of the pet.While it would be nice if every dog sat quietly without wriggling, twitching, scratching, whining or howling during a haircut, that's simply not the case. Give your dog the food and make sure it eats all of it. Continue to pet your dog until it reaches the desired stage of sedation.New places like a grooming salon are often a source of anxiety for dogs. Add a new person who's trying to cut the dog's hair or nails and the situation can become unbearable. But unless you're a veterinarian, don't try to calm your pet with chemical-ridden sedatives. Instead, try one of several natural pet sedatives that will partially or completely sedate your dog before a haircut. Partial sedation means your dog will be calm but drowsy. Place the recommended dose of your natural pet sedative in your dog's food or on a special treat.it puts the brain to sleep in both animals and human beings.This specific type of medication, which also includes anesthetics are used to either calm down a dog or put him or her to sleep for a short duration of time.The Lab might do ok in there until about 10 am or so... Those conditions are very unpleasant for dogs (high heat and humidity) and if you add a bit of anxiety in there, you are taking a risk. I'm glad you are asking ahead of time so you have a little while to try out some options. One of the things that I would strongly recommend is a DAP (dog appeasing pheromone) spritzer or collar. I would recommend purchasing some Composure Liquid from Vetri Science.If these were my dogs, they would be in the cab with me, even if that makes it crowded! It contains a smell that calms dogs, but is not a drug and is perfectly safe. It is composed of a protein extract from a milk product and a soy product plus a few other things.
