Most of the things I hate are outside influences. I hate listening to people give me the advice they learned from their Petsmart groomer, I hate listening to people give me nutrition advice from their Hill's sponsored vet, I hate listening to people give me their opinion about whatever dog I own (I have a family member that believes I shouldn't own a large dog because I'm 5'6" and 110 pounds). I REALLY hate mediocre owners telling me how I should raise my dogs. In person, though, I am too sheepish towards strangers to tell these people to pop off somewhere else.
As for the dog itself... I hate grooming, and yet I seem to prefer breeds that need a lot of it! Chows, Akitas, Malamutes, it's not the shedding that gets me, it's just the act of regular brushing. I hate even brushing my cat, if we're being honest. I hate brushing my own hair, too.
I hate shopping for food, too. Whenever we get a dog, I'm going to be buying dog food in as bulk quantities as possible. I hate going to the pet store or grocery store in the pet food areas and seeing people grabbing bags of Disney brand dog food, or Ol Roy or Science Diet. It bothers me more than it should, I know, but ever since learning about pet food I feel sick when I know a dog is being given a horribly low quality food (or any animal for that matter).
I hate vet visits. They scare me. No matter how mundane a vet visit is, for some reason I get horrible anxiety and prepare myself for some incredibly horrible news. "Good news is we got your buddy's nails trimmed and teeth nice and clean. Bad news is we found fourteen cancerous tumours and a set of silverware in his stomach." I'm a paranoid parent, no bones about it.
I love drooly dogs, I really do, but I HATE drool. While spending some time with a Saint Bernard named Pippa, I stepped in multiple giant PUDDLES of drool. I already have a very weird cat food syndrome on non-carpeted floors (it's worst on kitchen floors, where spills are so common or food is usually found), but the idea of stepping in, or slipping in, a puddle of dog drool just EUGH.
Man, reading through this I feel like I should go see someone, LOL.
