Do we have a how to post on making a week sprayer shower like canine has built, on this website?
I had described it before, but since it is so easy and quick, I'll do it again. First, pick your choice of weed sprayer. I've used a gallon size and that was fine for just me, but it wasn't enough for the dog. 2.5 gallons is a great size as it isn't too big and stands a bit higher so you don't have to bend down so far to pump it. I use 35 pumps for me and that lasts the entire shower (not so with the one gallon size). The size of the weed sprayer isn't just how much water it will hold, it is also how much air it will hold. If I can shower without stopping to pump, that is a more enjoyable shower. My 45 pound dog with medium length hair and no undercoat takes periodic pumping and about 1 1/2 gallons. Hair is harder to rinse out that's for sure.
Pick up that sprayer head that I posted or use one off of an old shower sprayer. Many companies use the same head when making their own battery powered showers. I've even seen them in orange. Then glue all the holes except 12 to 8 of them. Use gel super glue; standard viscosity glue will run and cover more holes than you want. No matter how careful you are, it will run if you don't use gel.
Cut the spray wand off of the weed eater- it doesn't need to be pretty. I like about 3 feet worth of tubing because I hang my weed eater about three feet up. 6 feet is more like it if you set the sprayer on the ground. The longer the hose, the more heat it will suck out of the water at first. If you need more length, just use nipples and hose clamps to splice more hose in. Some of the wands you may be able to unfasten, but many are a permanent attachment. Then buy an adapter (see link below) with a 1/2 inch threaded end and a barbed end. The threaded end will screw into the shower head. You may need pipe tape or pipe goop. The fewer leaks the better. The barbed end will need to be 1/4 inch or 3/8 depending on the size of the tubing on your weed sprayer. Actually, either size you can make work, so if you get the wrong size, you aren't out of luck. If you have a small hose but the large barbed end, you can jam the tubing onto it, but it can be HARD! Use lube of some sort. If you have the large tubing with the smaller barbed end, just scrinch that hose clamp down real tight. Use a socket with a ratchet instead of a screwdriver if you plan on tightening it that much. Get a good hose clamp, too- they are cheap. I prefer the nylon or plastic adapters over the brass, but either will work. Plastic is cheaper. I have a nylon one and have no issues with strength, but other plastics may be to brittle. Here is a link for one kind:

The weed sprayers with the wide mouth openings are harder to screw tight enough and to loosen. I have decent arm strength, so I could see that being be an issue for others. The smaller openings are just fine to pour water into; I barely spill, if any, with mine. The shower head does not shut off all the way. That is the way ALL of them are made. It is a piddly amount and amounts to almost nothing, so no worries there. I use 32 ounces or less per day, so it can't leak that much. I prefer 1/4 inside diameter tubing because the hose will suck some of the heat out of your water. The difference between 3/8 and 1/4 is noticeable the first few seconds.
