Some people are and some people aren't dog lovers. My OH is not "fond" of any animal in general due to his allergies and OCD cleanliness. Dog's can be messy, they chew as puppies, and it takes time to potty train them - it's work. What everyone says when they say "a dog/animal is like having a baby" is very much so true. They need constant attention, play time, walks, baths, feeding, watering, toys of their own, physical stimulation (varies based off breed and dog's specific needs, etc). But I believe in my heart animals were put on this Earth to teach us love and be forever friend's.
With that being said and being an avid pet owner (I have had dog's all my life and grew up in a household with 3 dog's) a dog does not stop being a puppy for about 2 years. My Mother has 3 very popular breeds in the US. A miniature shetland sheepdog, a chocolate labrador retriever, and an Australian Shepherd - they are all well know trainable dog's that are highly intelligent. Her house is a zoo to be quite honest. She has to vacuum and mop daily because they track in dirt and shed like crazy (the labrador sheds the most). She also had to replace her carpet due to them ripping it up, has to keep food in the microwave or oven because they will go to any length to grab food from the counter, she had to replace her cabinets because they chewed them to bits, on every corner edge in the house they chewed the wood lining so they had to replace that, and they also have ripped up expensive things such as an Ipad, Iphone, phone chargers, TV cord, window blinds/sliding glass door blinds, MY digital camera, shoes, socks/undies, and so on. Now they are all about 5 years old and are well behaved but still messy. Water is splashed across the floor from the drinking, they leave bits of dog kibble strung about, and they stink up the furniture/carpets.
Of course, keep in mind my mom has 3 dog's. So my BEST advice to you if you were to get a dog is 1. adopt from a shelter, 2. have several play dates with the dog before brining him/her home, 3. research the best suited breed or ask for guidance from the breeder/humane society worker. My knowledge of dog breeds tells me instinctively the best pet for you would be a small hypoallergenic dog. This insures less messes, smaller poo's to clean up, minimal shedding, and minimal physical stimulation. However, most hypoallergenic dog's have long coats (because they are crossed with poodle/yorkshire terriers) and require special hair maintenance. You can take the easy way out and have the pup groomed 3x monthly with a shave down. It took my poodle/shih tzu's coat 3 months to grow out after a shave down but she did require monthly facial trims from the groomer to prevent eye infections from over grown hair on the face.
With all of that being said, I respect you for not agreeing until you know you're ready and also researching and educating yourself. Every breed has its "pros and cons". Labradors shed, need a lot of walks/exercise, and eat a ton but they are friendly, great with kid's, and are wonderful jogging companions. Australian Shepherds suffer from anxiety, are hyperactive, and need "jobs" to be mentally and physically stimulated but they are loyal, intelligent, gentle, and are motherly with children. Mini Shelties need daily brushings, daily walks, and can be quite timid of strangers but they are sweet, quiet, loving, and great bed warmers.
Take your time and ask a million questions. Factor in the cost. A 15 lbs of holistic dog food (so important to have a healthy diet) is about 45 US dollars, yearly shots range from 50 - 150 dollars, microchips are 35 dollars, spay/neuter ranges from 50 - 400 dollars. But if you adopt the dog is usually UTD on shots and fixed. Then you need supplies such as a sturdy but comfortable collar, leash appropriately sized for the dog, bones/treats to praise good behavior and provide a form of oral hygiene, toys/balls/tug ropes, a cage if you want to incorporate kennel training, and so on.
There is so much that goes into animal ownership if you're a responsible pet owner. It can be costly and time consuming but at the same time it's heart warming and beautiful.
I wish you the best of luck with whatever decision you make. Any questions PM me.
