Plastic bag and then the garbage can.
One time I was walking about a mile away and my dog (60 pounds) dropped a load in his "usual spot". I picked it up and dropped it in the first trash can I came to, as the garbage trucks were close by and I really didn't want to carry it around for another half hour or so. My dog and I walk past one of the "old crazy bastard" houses where the old coot living there is way way way too into his yard. We never stopped, and my dog never hiked his leg, even on the rock he has along the curb engraved with his address, where EVERY dog does..
About ten minutes later, the old guy comes flying up alongside me in his car, and starts cussing me out. He's saying he's going to call the police because my dog supposedly dropped a load in his yard a few minutes ago. I tell him I put the bag in a garbage can and my dog went at least a quarter mile away. He calls me a "f'in liar!" and so I tell him to meet me back at his house, I want to see it!
He's pacing up the driveway when I come around the curve and as soon as he sees me, he runs over to a huge pile in the yard. It had to be a 100+ pound dog's load, minimum. The "diameter" was 3X my dog's, and it was obviously, not "fresh". I laughed at him and said "You think THAT came out of THAT dog?" "You're crazier than I thought you were!"
He was so angry, I thought he was going to hit me, and screamed, "Your dog did that,a nd you know it!" We went back and forth and his neighbor comes out and walks over to us. He tells her his side and I laugh, and he's getting steamed. After he's done, I say to her, "Look at the pile he says my dog made, and tell me he's not crazy!" She looks at it, and says "It's been there a while, and is from a really big dog, not this one!" He got seriously pissed at her, and she left.
We yelled at each other for a couple of minutes and finally he tells me that if he sees my dog walking on his yard he's going to shoot it. I just walked away, laughing, then said, "Do it, you crazy bastard, and I'll own your house after I sue you!". I would be suing for shooting at me, while walking on a public street with a 3 ft curb access along the front of his yard.
After a few months, I thought it was all settled, then I'm in the checkout at the drug store and he comes up and starts screaming at me, saying I'm taking my dog out and having him crap in his front yard every night. I just look at him for a while, than tell him my back has been bad and I haven't walked him in several weeks! He is totally out of control, and as he leaves, "I know it's your dog!" When I came out of the store, he pulls up and starts yelling at me again. There was a cop there and he told the old man that he should "save the pile" for a DNA test! I said, "Great, then maybe he would shut up and stop this nonsense!" He was yelling at me as I left, and after I got home the cop showed up and explained that he has accused dogs of all sizes over the 30 years he's lived there of being the ones that crap in his yard, and that I should just avoid him as best I can.
Over the last couple of years, I have pretty much been able to keep away, but a few weeks ago, he pulls up in his car, and starts yelling that my dog just crapped in his yard again! I had more than I could take about this and had the bag in my hand, so I just tossed it into his car and told him to eat it and die, "make me and your poor wife both happy!"
He called the cops because I tossed it into his car and the same cop shows up as did two years before. He listens to his raves and then picks up the bag, (it's still warm), and then chews him a new one, "For harrassing this man, obviously his dog didn't do it today! I see him picking up his dog's loads all the time when I pass by him on patrol, so I doubt it was him the first time you started the crap a couple of years ago!" "What the hell is wrong with you anyway? A little dog crap isn't gonna hurt your yard, it's FERTILIZER, for god's sake!" "If I come back here for this again, YOU WILL GO TO JAIL!" The old man starts to say something about the pile in his yard. The cop looks at it, and starts yelling again, "That turd's as big around as King's leg you idiot, a dog doesn't drop a turd the diameter of his damn LEG!! The old man's like, "Well, uh, uh, I,.." Then he thinks he figured it out and says "Hey, how come you know his dog's name?" "You and him are buddies, arent you??!!" The old guys wife comes out and basically said, right in front of him, that he wasn't right in the head and had been staying up all night, trying to catch me and my dog going into his yard. I chuckled and said, "I work all night, 5 days a week, so that's pretty pointless". The cop told his wife what the situation was and I left.
About an hour later, I was in bed and the answering machine comes on, I had forgotten to turn the volume down, and the old man's on there saying, "You and I both know you are coming into my yard every night, and one day I'm going to catch you!" OK. I called the cops and asked the dispatcher to have him call me, and a few minutes later he did. I played the message for him and he went over and explained the situation to him and his wife again, and told her that he would try to have her hubby committed for a psych evaluation if it didn't stop right then. "Obvously, you are out of control!" He still argued with the cop and insisting I was coming into his yard every night. He's now saying me and the cop are "in cahoots with each other" to make him look crazy. He doesn't need help doing that!
Well, the problem solved itself a few days ago, I saw an ambulance turn into his street and had to see where it went. It pulled into his driveway and I saw his wife open the front door and they took the crazy old guy to the hospital, he had a stroke, a bad one. He's not coming home again. The "For Sale" sign went into the front yard a few days ago.
Yipppee! I don't really feel sorry for him at all.
