Are you a dog person?

I can honestly say that I am. I love dogs and I have every since I was little. And I also believe it's good for little kids to have pets. When we got our first dog, Samantha, we had no kids, were newly weds, and lots of free time. We spent months potty training and coddling her. She slept at the foot of our bed. She peed on command, she even knew how to fake pee so she could get a treat. When she got sick for 3 days and wouldn't eat anything I was crying on the phone to the vet. But we had Savannah and moved to Lancaster and Samantha was taken from our yard. Since then we have gone through 3 dogs and 1 cat. And now our latest victim- Ruby. For those of you who have met Ruby, you can attest for her cuteness. Its the so ugly she's cute type. Wire haired and super sweet. But likes to bark when the kids are asleep. And likes to track mud onto my hard wood floors. And scratches my sliding glass doors right after I wash them. She also likes to play this game where she goes out the front door whenever she has the chance and runs as fast as her tiny legs will carry here (which as a side note is faster then my normal sized legs) all the way to the main busy street like 4 blocks from my house. It's a normal day when my neighbors on either side or complete strangers are knocking on my door asking me if I know the dog they found. It is also super neat when the dog gets into the trash can and rips apart a poopy diaper. Or when Savannah leaves her brand new Crocs outside and she chews them up. Well the final straw was yesterday. We left the door open (I know that is my fault but Mike can't drop me at the pound) while I went to the Arboretum in Pasedena. Creed cried the whole way there and it was pretty stressful. He also cried the whole way back. After 40 minutes in the car and him screaming which I am not used to since he never cries, I was so happy to get home. But the smile on my face was short lived when I realized there was dog poo in both of the kid's room and pee in the baby's and the bathroom. As if I don't have enough bodily functions to clean up around here. And there Ruby was, laying outside nice and comfy on a pillow that Mike had set up for her, napping while Creed was screaming and Cole was still in the car sleeping since I had brought the baby in first. Napping on the porch. Guess she prefers the softness of the carpet while she urinates. Or maybe the grass was scratching her bum while she pooed. Either way it was a life altering mistake for her because when Mike got home at 4:30 she was all packed up ready to be dropped off at the shelter.
Do I feel guilty? When Cole went outside 10 minutes after Mike had gone and was yelling for Ruby and asking for Ruby and telling me Ruby was hiding, it tugged at my heart strings. When Savannah prayed that Ruby wouldn't forget her I thought seriously about going to get her. But I quickly remembered all that I have on my plate right now. And I'm not one of those people who can do it all, I am just trying my hardest! So even if you are turning your nose up right now thinking what a meanie, I don't care. I still believe kids should have pets. Maybe a goldfish.......
