Generally, both males and females make excellent service dogs. Some handlers prefer one gender over another, but the only time it really matters is if a larger dog is needed in order to perform weight-baring tasks.
Gender: While there is no set rule that a female dog will be a better friend for a male dog, if you have never had two dogs at the same time it is generally easier and often safer to have dogs of the opposite sex. Same-sex combinations can be tricky to manage as dogs work out their dominance or pack order.
Many dog people say male dogs are more affectionate, while female dogs tend not to want the constant attention and validation that the boys often seem to crave. They say female dogs can be "moody" and "independent," while male dogs can be "clingy" and "silly."
Female dogs tend to be easier to housebreak, easier to train, and more connected with their owners—but in certain circumstances they can be more demanding of attention. Aggression can be a problem in any dog of any breed, however it is usually more apparent in non-neutered males.
Explaining Behavioral Differences in Dogs
Male dogs are genetically wired to be hunters; females are nesters and therefore may be better with spatial reasoning. Researchers are also quick to point out that no difference was noted in neutered or non-neutered dogs.
Some dog owners claim that males are typically more aggressive and destructive, particularly in small spaces. Female dogs are said to be easier to train and more affectionate. Depending on the dog breed, these stereotypes may be true or not.
One long-standing myth about dogs, is that female dogs tend to be more loyal than their male counterparts. This myth has passed down generations of dog breeders and dog lovers. And can be traced back as far as when dogs were wild and living in packs.
Dogs are inherently social animals that live well together in groups, but that does not mean that all dogs get along. Most dogs will welcome a new sibling, but it is not always smooth sailing. The furry family member you have now will face many changes when a new dog enters the picture and may feel a bit displaced.
Having two dogs can feel like a lot of work sometimes, but the pros definitely outweigh the cons. From easier training to better mental and emotional health (for you and your dogs!), to saving the lives of animals, there are so many solid reasons to adopt a second dog today.
In dogdom, there's a turn of phrase called, "Second Dog Syndrome". This describes the process of adding another dog to the home quite well, but not necessarily in a positive light. As humans, we are bound to forget all of the time and effort it takes to raise a puppy right.
Two dogs can share toys, beds, grooming products, water bowls, larger bags of food, and treats. Safer for you and your furry family members. Two dogs protecting the home are better than one. Also, when you have two pups, they will take care of each other.
Female dogs tend to be more responsive to training and are often less prone to wandering off or trying to swap training time for cuddling time! They are also better at socializing with other dogs, which can make it easier when you're out and about trying to reinforce training.
Whether or not dogs are more attracted to one gender can't be objectively answered because all dogs and people are different. But, dogs generally tend to be more attracted to a specific set of behaviors that are exhibited mostly by adult women. It's not that dogs are exclusively attracted to female adults.
Scott and Fuller wrote in the 1965 Genetics and the Social Behavior of the Dog that males grow larger in early adolescence, and that sex does have an influence on “emotional reactivity,” even though the scoring between genders was very close. Females scored 5.0 on their reactivity scale and males a close 4.9.
This varies from breed to breed and some male dogs can also be very loving and protective of children. Male dogs are most often more affectionate and seem to thrive on constant human attention. They are usually less likely to separate themselves from the attention and will take any bit of love you can give them.
Cons of females include higher neutering expenses, responsibility to avoid randomly breeding offspring, as well as managing a female dog in her heat.
Like humans, dogs are especially impressionable as their brains develop, so puppies up to 6 months old are in their key socialization period. Like their human counterparts, dogs develop favorite people over time based on positive experiences and positive associations with that person.
Dogs are social animals and usually happier around other dogs, but a second dog will never be a substitute for inattentive, absent or too busy owners.
Allocate the Time and Resources for Another Pup
You also have to keep in mind that you'll need to invest extra for essential gear — collars, leashes and crates, to name a just a few items — as well as unexpected vet visits, potential boarding and possible pet sitters and dog walkers.
They enjoy friendly interactions with familiar humans or other animals and tend to avoid isolation. That being said, every dog is different has its own temperament and preferences. Some dogs prefer to live alone with their owners, while others prefer having another dog friend in the house.
For example, if you get a new pet and start paying it more attention than your dog, the dog will not feel betrayed in the true sense of the word. However, it may show signs of distress and disappointment because it is suddenly being treated differently or being deprived of something it is used to getting.
Getting your dog a companion usually doesn't help an anxious dog because their anxiety is the result of their separation from you, not just the result of being alone.
