Taking Your Dog To The Lake – Common Considerations

Taking Your Dog To The Lake – Common Considerations

When you take your dog to the lake you can be exposing them to a TON of fun and healthy exercise but there are some other things to note.


Okay now THIS is a rarity in the extreme. I heard about this in Vet School in 1991 where it had killed some deer next to a farm pond. The next time I heard about it was just this year (2019) and it came and went as a “thing” and I kind of think it was blown out of proportion as on rare occasion, the media does. One case was reported but unconfirmed, and the lake in question tested negative. But, it happens. It wouldn’t hurt to stay out of water that seems ‘stagnant’ or which contains a dark algae floating at or near the water’s surface. The algae doesn’t tend to be in full sun and it prefers clear water without much depth. (Article)

Oils in the water

This issue is pretty common and causes irritation to the coat until the pet is bathed thoroughly. When a two stroke boat motor burns the ‘gas oil’ mix, it puts a tremendous amount of pollution into, and ONTO the water. The stuff kills ocean reefs and that’s why two stroke engines aren’t allowed within miles of precious barrier reefs all over the carribean. In any event, this gas oil combustion byproduct floats on the water and creates a brown film on the piers, and pontoons on the lake. And when your kids or dog spend the day in and out of the water, they get this irritating mix on their skins and coats. Well, the kids take a bath, and your dog should too. Otherwise it could be an itchy deal for the dog.

Ear Infections

For some dogs, water left in the ear can set up infections about 2 weeks later. They start in the horizontal canal and eventually you can see the redness and itching creeping up the vertical canal about a week or two later. Dogs with ear flaps that stick UP seldom have a problem with water in the ears. But dogs with ‘dependent’ or droopy ears or who have a lot of hair growing IN the ear, can have ear infections from that. You can attempt to dry the ears after the weekend at the lake, or even apply something with a soothing ‘oil’ in it, to repel water. Zymox is a favorite of mine, if you even do anything at all. A decent ear cleaner also can work because they remove various contaminants (as listed above) that may be residing in the ear. If your dog is prone to ear infections and you already have a bottle of Gentizol, GenOne, Entederm, Mometasone, Panolog or similar oily medication for yeast and bacteria, that could work preventatively as a single dose after swimming. But the key is “oily”


Overexertion, or “tying up” can happen if a dog swims or runs around a LOT more than usual. The muscles get deprived of oxygen and the muscle fibers get overtaxed and the combination causes some of the muscle fibers to die. This causes muscle pain, stiffness and a serious reluctance to move around. Hydration is key the next day and the vet may even decide to run some fluids. Bloodwork can detect a high CPK level and the urine may be dark. This is seldom fatal. So just watch it, especially if your dog isn’t really THAT active and you suspect that THIS weekend, he will be.


Drowning’s uncommon as well. In fact, I’ve only ever heard of one of my patients legit drowning and that poor dog had a seizure and fell into the pool before the owner could rescue her. That was sad. At the lake, I almost lost my own dog because he wasn’t wearing a life preserver. He was older, and a weak swimmer and we had turned the boat around after he jumped in, and we made it just in time as he was sinking low in the water. Another dog hit his head and almost drowned. My point is (hence the referenced article) to put a life preserver on your dog at the lake. ]

Or YOU Drowning

You know, like your dog gets on you in a panic and drowns you.

Know Your Snakes

A solid nine out of ten snakes you meet at the lake (United States) are Northern Water Snakes. Not copperheads or water moccasins but you never really know. Unless you know. Learn the snakes. By-and-large the poisonous snakes have triangular heads far wider than their necks. And they have slit-pupils (like a cat) as if you’re really going to stoop down and check THAT out, huh? ha ha ha!!

This is a Water Moccasin. Also called a Cotton Mouth.
This is a copperhead and they don’t like water, and they have a big wide triangular head. Their pupils are slits.
Northern Banded Water Snake note the narrow head and by the way Copperheads hate swimming.

This is The LCD Screen Scope
We Did The Tutorial With. I did a twenty page tutorial (Here's the tutorial) with video, audio, images and even little parasite movies to show you how to use a microscope. 

This Filter is Good For BIG Dirty Tanks
I've been wrestling with water quality with the turtles. The sponges work GREAT, but in THOSE turtle systems where they eat MICE the poops are bulky. This filter can handle it. In "Tortu's" tank, it's got an 800 gph pump and it rocks. 

PraziPro for Flukes
They nailed it. Figured out the solubility and worked out the dosing. It works. 

Buy Some Good Koi?
No, this isn't really for the 'high end' collector y'all. But for someone who isn't near a decent garden center, here are "good-to-quite-good" Koi you will like at a very good price. I know these guys personally.

Best Food, Ever
It's made for (and I discovered it for) my Blood Parrots but the small size, intense color enhancers and excellent formulation make it superb young-Koi food. Oh, and it's AMAZING on color-cichlids like Flowerhorn and Blood Parrots. 

Pro Air 60 Aerator is a VERY high output air pump pushing my whole fish room (17+ drops), and I have one at home driving everything there, and I have one as a back up. 

Formalin Malachite (Not dilute)
There are formalin malachite preparations at 10%, 22% and 37%. There's economy in the concentrates. Hard to get Prime shipping because air transport is curtailed. This is a good value on 32 ounces. 

Topical For Koi and Pond Fish Ulcers
I like 7% tincture of iodine because it stains but it's hard to hurt anything with it. Used with a WOVEN gauze, this works well to clean and disinfect a wound. Only use ONCE. Do not 'repeatedly' scrub wounds. 

Confectioner's Glaze 
Is the way to bind a medication to fish food. Gone are the days of paste food and oil. The write up is done, it's RIGHT HERE.

Koi Health & Disease
Hopefully this link takes you to the newest edition by PRIME to get it to your house the fastest. 

I have over ten of these Titanium Heaters in my fish room and at home. They're a paradigm shift in aquarium heating. They're titanium and 400W for under $30! Whaaaaaaaaat?

CyroPro by Hikari is safe and easy for Anchor Worms and Fish Lice.

Whatever heaters you use, back yourself up with a temperature controller, it'll turn on, and off your heaters. If your heater seizes "on" at least the thermostat will stop a tragedy. 

LifeGuard by Tetra is a tablet version of a tame 'chloramine-t' or 'halamid' compound that's easy to get and good on bacterial infections, in baths. 

If you're making medicated feed for a larger group of fish, this will come in handy. Dosing is available in the site. 

For me, filtration-of-choice
For aquariums, even small Koi holding facilities or small ponds. These sponge filters are cheap, easy to clean, and they clear hazes very well when used with some Accuclear or similar.

Rubber sided, round, nettable tanks
Make great hospital or quarantine facilities. They SHOULD cost about $200-300 depending on size, but this, lower quality unit (while panned in some reviews) may be good. Don't overfill and make sure it's propped up.

1200 Watt heater, on a thermostat held securely above the waterline, works GREAT as a large tank heater. That's all I'll say because there's risk of electrocution and all that. But then, even in a bucket you could get killed. Sound like fun?
I have several of these ALLIED PRECISION stainless ones that are a couple years old. Working still. 

Potassium Permanganate 
500 grams could be a lifetime supply but it's 50% more than the 100g cost wise, for 500% more amount. Dosing is in the site and the book.

What Does Ajax Eat?
I looked for something well formulated, with meat as the first ingredient. Something UNDER $2/lb and something they could deliver for free. And this was it. He looks and feels great on it.
