Your dog needs more water on a hot summer day than a cold winter day as you already know.
So when you are out on your walks with your pooch make sure you have a source of water handy in case he/she gets overheated and thirsty.
Signs of Dehydration:
When your dog loses too much water he/she also loses important minerals and electrolytes which can be deadly to dogs in extreme cases.
Some easy ways you can check to see if your dog is dehydrated:
Skin elasticity test: Pull the skin on the back of your dog's neck a bit. If the skin goes right back into place that means he/she has enough water.
If the skin takes a few seconds or more to go back into place then your dog is likely dehydrated.
Capillary refill time: Another way to test your dog's dehydration level is to do the capillary refill time test.
Don't worry...it's easy!
To test this, simply push against your dog's gums until they turn white then remove your finger.
If the color quickly returns to the gums that's a good sign. If they stay white for several seconds that could mean he or she is dehydrated.
Just like in humans, dehydration in your dog can be deadly so if you think he or she is dehydrated call your vet immediately.
An easy way to make sure your dog has enough water if you are outdoors with them is to get a portable water dispenser.
