Make sure you get the sugar-free kind of Kool Aid. This works better for dyeing. Remember that the dye will fade over time. Choose a color that you will still like as it fades. For example, red fades to pink after a few weeks.
Conditioning your dog’s hair will also help your dog’s coat be less tangled and easier to comb out. [1] X Research source
You could even do it in your bathroom if you take the proper precautions ahead of time. Put down some old towels you don’t mind getting dirt or dye on.
You should use the same amount of conditioner you would normally use on your dog, which will vary depending on the size of your dog. Use on or two packets of Kool Aid powder depending on how big your dog is and how vibrant you want the color to be. If you have a large dog and you want a very vibrant color, use two packets. If you have a small dog, use one packet.
You could dye your dog’s head red and its body green for Christmas. Or you could dye your dog in red and blue stripes for the 4th of July.
Always use shampoo that is made especially for dogs, not human shampoo. Lather up your dog with the shampoo and rinse it out.
You can use a dog brush or comb to make sure the mixture gets through the entire coat or to create patterns. For example, you can use a brush to make clear lines or breaks from one color to another. Let the dye/conditioner mixture sit for 5-10 minutes on your dog, being careful not to let your dog rub up against anything you don’t want dyed. Make sure to wear protective gloves during the whole process to keep your hands from getting any of the dye on them. Otherwise you might end up with splotchy blue or green hands.

Use a towel to help soak up any of the excess water and then let your dog’s coat air dry. Once the conditioner mixture is rinsed out, you can see how vibrant the color will be. If the color turns out more faded than you would like, feel free to repeat the conditioning process so that the color becomes more visible.
