Has your dog eaten human hair? Are you worried the human hair will make your dog sick? If so, then you’ve come to the right place. We understand it’s scary when your dog eats something he shouldn’t.
In this article, we’ll take a look at human hair and whether or not it can make your dog sick. Let’s get started!
Why Do Dogs Eat Human Hair?
There are several reasons dogs might eat human hair. For one thing, they may see a clump of hair on the floor and start to play with it. The dog may then become curious and try to eat the human hair. Yuck!
In puppies, they’re probably just exploring their new world! Puppies are curious about everything and may see the hair and play with it. While they play with the hair, the puppy may take the hair in his mouth to get a better idea of what it is. It’s at this point the puppy may accidentally swallow the hair.
Some dogs have a condition called pica. This is a behavioral condition that causes dogs (as well as humans and other animals) to eat non-food items. Some dogs may be bored, suffer from separation anxiety, and more. However, there are also dogs with pica that may have a nutritional deficiency or may not be getting enough to eat. This may cause them to eat non-food items such as human hair.
Eating human hair is a common issue in dogs; however, can human hair make a dog sick?
Human Hair & Dogs
A little bit of human hair is not going to make your dog sick. However, if your dog eats a large amount of hair, he could develop a serious health issue. Large amounts of human hair in the dog’s digestive tract could ball up and become stuck. If this happens, it may create an intestinal blockage. If this condition is left untreated, it can lead to death.
Another problem is if the human hair is covered in any hair products. Some of these can be toxic to dogs.
