Traveling with dogs can be stressful. Throw in holiday home stays at one of the most chaotic times of the year and 鈥� especially when hosts have pets of their own.

Large gatherings, unfamiliar smells and sounds, mixing older or sedate dogs with energetic pups, and introducing small children or cats to a dog with no prior exposure are among the issues that can spoil the experience or, worst case, cause physical harm.

But tensions can be dialed way down with a little preparation, said certified dog behaviorist Gabrielle Johnson of Richmond, Virginia. Knowing when to pull the plug and head for a pet-friendly hotel or boarder is also key.

鈥淐ertainly holidays can be a tricky time because everyone鈥檚 out of their routine, out of their schedule. We鈥檙e in tight spaces. Stress is high,鈥� Johnson said.

Johnson warns that dogs that are typically fine at home . Learning to is important.

鈥淭hings like yawning, licking their lips, turning away, looking away, freezing, getting tense,鈥� they said. 鈥淲e want to see soft, wiggly, loose, relaxed. If we see some of those (other) signs, it may be an indicator that it鈥檚 time to get our dog out of that situation.鈥�

Taking a crate along is a great idea for already crate-trained dogs but don鈥檛 try to force it for the first time, trainers said. Packing a bed and familiar blankets, toys, dishes, and food and treats are musts.

First-time introductions between dogs should be done on neutral ground, outdoors. The humans should plan ahead in case pets need to be separated, including considering baby gates, particularly when dogs are eating. Owners who suspect anxiety might be a problem could consider medication.

Nicole Ellis, a certified professional dog trainer for Rover.com, suggests practicing with dogs who have not traveled much. If a dog is going from a quiet rural area to a noisier urban environment, take a few shorter trips to simulate the holiday surroundings, she said.

She also advises packing mental enrichment toys to help a dog decompress and navigate a new environment without getting rowdy. Licking and chewing also help a dog self-soothe, Ellis said.

James Paasche of Central Point, Oregon, will spend six days in the San Francisco Bay Area with his wife, 6-year-old daughter and 11-year-old dog, Walter, for Christmas.

Paasche鈥檚 brother has three dogs of his own, including two older ones. Walter, anxious his entire life, has met only his younger canine cousin. He takes medication but once nipped at a child on a previous stay at another home. The children of Paasche鈥檚 brother are older, but he鈥檚 concerned about the two new dogs.

鈥淵ou know how it is with older dogs, they get a little more set in their ways and are less amenable to new things that puppies and younger dogs just don鈥檛 care about,鈥� Paasche said. The hosts have a garage for Walter if things go awry.

Dr. Jamie Richardson, head of veterinary medicine for Small Door Vet in New York, said keeping a dog鈥檚 diet consistent should be top of mind.

鈥淭heir GI tracts can get upset very easily with change,鈥� she said. 鈥淒on鈥檛 assume your food will be available locally.鈥�

Richardson said dogs should be introduced to young children slowly and very carefully. If toddlers don鈥檛 understand the concept of leaving a dog alone, they should be separated.

Home stays aren鈥檛 all gloom and doom, though.

Phoebe Yung of Brooklyn adopted a pandemic pup, a rat terrier named Moose. She and her husband travel with Moose often, including long trips to Europe. The holidays have them driving to Montreal to stay with relatives 鈥� including two young children 鈥� for six days.

鈥淲hen she sees her pet carrier she jumps right in,鈥� Yung said of Moose. 鈥淲e really try to follow the rules of any house we鈥檙e in. We bring along a mat, and when she鈥檚 sniffing around a new place and seems to find a spot she鈥檚 comfortable with we put it down and that鈥檚 her spot.鈥�

Young children scare Moose, but she runs away and shakes in a corner rather than getting aggressive, Yung said. She added that she would step in if Moose gets too stressed.

Emily Keegans, Seattle Humane鈥檚 chief of animal behavior, said dog owners should ask themselves if the situation is going to be a happy one for their animals, and communicate with hosts.

鈥淚f I have friends or family come to stay at my house, my first question is 鈥楬ow does your dog get along with cats?鈥欌�� she said. If the answer isn鈥檛 promising, she鈥檒l put her cat in another room and talk through logistics.

Lily Hargis lives in Richmond with Milo, the Labrador-Australian shepherd mix she rescued last year. She spent her last three Christmases visiting her great-grandmother 鈥� who has no pets 鈥� in Oak Ridge, Tennessee.

鈥淚鈥檒l never forget the stress of that first holiday with Milo in her home, how worried I was about his behavior being perfect and reflecting on me,鈥� Hargis said. 鈥淚 think it鈥檚 especially tough when there鈥檚 a generational gap.鈥�

Happily, her great-grandmother warmed up to Milo right away: 鈥淲ithin five minutes she had him up on the couch and in her lap getting cuddles.鈥�

This year, Christmas will be closer to home, but she has other worries involving Bourbon, her stepsister鈥檚 ancient pit bull who 鈥渨on鈥檛 tolerate any shenanigans.鈥�

To prepare, Hargis and her mother spent several sessions with Johnson, working on getting Milo and Bourbon to a place 鈥渨here they could comfortably relax in the space together.鈥�

鈥淚t just felt necessary,鈥� Hargis explained. 鈥淭here are so many aspects of the holidays that require our dogs to do things they really don鈥檛 practice much.鈥�

As soon as they arrive, Hargis will prepare frozen Kongs and other enrichment items to help Milo decompress in a quiet room.

鈥淗onestly, I sometimes get jealous of how well his holidays are curated to avoid stress and maximize fun,鈥� Hargis said. 鈥淚t makes me want to see how I can do the same for myself.鈥�
