No. Bed bugs are also pests in poultry operations, and they're known to parasitize bats. Some labs that study bed bugs rear them on guinea pigs and mice. The bugs might feed on cats and dogs. Fur is probably a barrier to them, but they could feed at any place on the body without fur. Bed bugs are not specific to humans, but they are adapted to parasitizing us.
Hey Jessica! Sounds like bed bug bites to me but don’t stress, although bed bugs are known to travel with you from other locations its not a guarantee that they always do. I recommend giving all your clothing a hot wash when you get back home (and your travel bags) and to inspect your bed for signs of their presence. As a precautionary measure, you can put DE under your sheets for a day or two and that will kill any pests that are hiding there. Good luck
But the bites will look different from person to person, and some people won’t develop any reaction whatsoever. “The same bedbug could bite two different people and one could have no reaction at all and the other can have an extreme reaction with a swollen arm or itchy rash,” says Eric Braun, a board-certified entomologist and business manager for the national pest control company Rentokil Steritech, who is based in Redding, Pennsylvania. Some people end up developing a rash that looks like eczema. (5)
Specks of blood on bedding, mattresses, or upholstered furniture such as couches and headboards: Look carefully at your blankets, sheets, and mattress pads and then check the mattress and box spring. Are there specks of blood anywhere, especially near the seams? If so, there could be a bed bug infestation. You should also check for specks of blood on all upholstered furniture, including couches and headboards.

Although treating bedbug bites isn't difficult, actually getting rid of the bedbugs is another story. A professional exterminator can help. You will need to discard infested mattresses, box springs, and pillows. You can heat treat or cold treat items such as clothing by laundering or freezing. However, the room itself will need to be treated to eliminate bedbugs that can live in cracks in walls, floors, and furniture.
A few decades ago, bedbugs were somewhat of a novelty in developed countries. But since the early 2000s, infestations have become more common in places like the United States, Canada, the United Kingdom and Europe, according to the U.S. Centers for Disease Control and Prevention (CDC). A 2013 study in the journal Nature Scientific Reports suggested that bedbugs have evolved ways to resist insecticides.
Bed bugs tend to congregate, but it’s also common to find a single bug or some eggs here and there. A thorough inspection and treatment may take up to several hours. Some companies use specially trained dogs to assist in finding small dispersed infestations, especially in such places as hotels, schools, libraries and office buildings. When properly trained, bed bug detection dogs can be quite effective. Relatively few companies are routinely using them, however, due to the expense of training and maintaining such animals. Reliability of some of the dogs is also being questioned as more enter the market.    
We kept feeling something crawling on us when we sat on tge couch. Then tiny bites Started appearing. After months of trying various cleaning approaches, we contacted Terminex. Their inspector found two bedbugs in the seams of a chair in the bedroom , but nothing on the sofa. They charged me a thousand dollars and steam cleaned both the bed, chair and sofa. About 10 days later, we started getting bites again. Terminex came and “dusted” the areas thus time. This continued for a a few months and them the “inspector” from Terminex said they could fund no signs of the bugs rhe last few times and he thought misquitoes were probably biting us. It has been months now and the problem has worsened. Now I get horrible welts when bitten and we constantly look for tangible signs: excrement, bugs in tape, anything before we call a different extermination company but life has become unbearable. We can’t have guests over because we fear they’ll become infected. It has been and is a truly awful experience.
Don't assume your bites are bedbugs. Bites can be hard to identify, even for doctors. Rule out mosquitoes, fleas, mites, and biting gnats by conducting a visual inspection. It's best to collect and identify bedbugs to confirm bites. Look for the bugs themselves or their bloodstains, especially along the seams of mattresses. Further, look for dark spots of insect waste where bedbugs might crawl into hiding places on furniture, walls, and floors.
Don’t forget that in some cases a person does not react to bed bug bites at all. It’s really not that easy to easily identify bed bug bites. Often a diagnosis of spider bite is given when the person really doesn’t know what is causing the lesion(s). Spider bites are often an over diagnosed condition. Also, a hot or warm dryer is much more useful than washing clothes in hot water. Certain studies have shown that some bed bugs will withstand the wash, but not the dryer.
