Why is Dog Dye Illegal in Some States?
Dyeing the hair of dogs began to become fashionable a few years ago. In Europe, it is not a very popular practice, but in cities like Tokyo, London, or New York, it is widespread to see dyed dogs.
But does this pose any risk to dogs? They can be funny, flashy, fun, but it can have consequences. We tell you the dangers of dying a dog’s hair.
Dogs with dyed hair are not a natural thing. In fact, with these practices what we are doing is “humanizing” the dogs, something that we should avoid at all costs because it makes it very difficult to educate pets.
Besides, dyeing a dog’s hair implies that it later has difficulty interacting with others of its kind. Remember that dogs recognize each other through smell; The moment one dog notices a strange or artificial smell in another dog, they will indeed reject it. Believe it or not, this takes a toll on your pet’s character and self-esteem. 
Finally, such drastic changes in their appearance can cause a dog a strange feeling, shame, stress, or even anxiety. Some dogs feel bad when their hair is cut, so imagine if it is dyed!
Animal Dye and Toxicity
Some dog dyes use natural ingredients and suitable for use on animals. However, there is little regulation in this matter in some States, so you have to be careful.
Many natural dye products, contrary to what their manufacturers indicate, are NOT suitable. The toxicity of its ingredients can cause discomfort, irritation, itching, or even burns on the skin of dogs. 
And the danger goes further! It means that a dog dyed with an inappropriate dye will be intoxicated, because the dyes will penetrate through his skin, in addition to being licked, he could swallow it.
If this happens, the dog will surely get sick, even with the risk of death. For these reasons, we must think very well if we want to dye our dog’s hair.
Is it worth it? And if you decide to, be sure to look for the law. Find a natural and non-toxic dye, as well as having a professional hairdresser who gives you quality guarantees.

Do authority vets recommend dying the dogs?
A vet may or may not recommend dying your dog depending on your dog’s health, skin condition, fur type, coat quality, and other concerns.
Although, they will suggest you that it is best and safe for your dog when it is done by a professional groomer and not by any untrained person. A professional groomer would know the best and non-toxic pet dyes that would not harm your dog in anyway.
Experts also suggest that it is best to do a deep research in finding the best groomer in your area to perform this procedure on your pet. You may also want to ask the groomer if you could see their past work photos or videos.
However, you may also want to consider your dog’s personality before getting his fur dyed. In some cases, your shy dog may not want to look like a cartoon character or a different animal that would draw more attention towards his appearance. This whole process and experience may cause him stress, which any pet parent would not want their dog to face.
We know that for you, your dog is a member of the family. But remember, it is not human! You do not have to give him the same treatment as people, nor do you give him our customs.
Some acts of humanization towards dogs are apparently harmless and straightforward, such as feeding them our scraps. But some people take it much further: dress them, take them with them everywhere in a bag, and now it is the fashion to dye the hair of dogs.
If you’re thinking of dyeing your dog’s hair, think about this: would he want to dye it if he could choose for himself? Does it bring any real benefit to your dog or are you doing it just because it’s “fun”?
If you do this type of thing, it is essential to assess the character of our pet very well. For example, if your pet is shy or if your dog is fearful, we would not recommend dyeing its hair at all: it will look and smell different, it will cost more to make your dog gets back to its state.
