H2O4K9 Bottles come in two sizes. The large bottle holds 25 fluid ounces and the small bottle holds 9.5 ounces. The 25oz. Bottle's lid will hold 8 1/2 fluid ounces per serving, although we recommend serving less water, more often. The 9.5oz. Bottle's lid holds 3 fluid ounces per serving.
A dog will need to drink about an ounce of water for every pound of weight daily, but may need more if he has exercised, the weather is warm, or he is taking medication that may dehydrate him.
Salt water is dangerous when ingested in anything more than a very small quantity, because the salt can raise blood sodium to dangerously high levels, resulting in neurological problems and even death in some cases. Dogs who drink sea or ocean water will often get sick and have loose stools.
There was a time when it was safe for humans and dogs to drink out of clean rivers and streams, but the Giardia bacteria has been found to be in most natural bodies of water. Humans and dogs are advised not to drink stream and lake water because of illness causing Giardia, viruses, parasites and bacteria. It's important to bring bottled water for you and your dog when you are going on outings.
H2O4K9 water bottle cannot be frozen or the welds will break, however the wide mouthed bottle allows you to put ice in to keep the water extra cool.
304 stainless steels is the same as 18/8 stainless steel, which contains 18% chromium and 8% nickel.
Stainless steel is basically made stainless by the presence of chromium in the alloy. To qualify as "stainless" steel, it must contain at least 10.5% chromium. Chromium reacts with oxygen in the air to create a sort of "self-healing" chrome-oxide surface layer that resists further contamination (rusting) by oxygen. This layer is not bullet-proof, and can be permeated. The presence of iron actually prevents this protective barrier from re-forming.
The wide mouthed H2O4K9 water bottle allows for simple hand washing. For best performance, we recommend washing the H2O4K9 bottle and lid by hand. You can remove all normal contamination from the material using a non metal bottle brush, similar to the OXO Tot Bottle Brush.
Do not use carbon steel brushes, or brushes with a metal rod or tip that can scratch your bottle. The oxide barrier can be breached and will then need to be treated correctly, otherwise you'll think you just cleaned your bottle, only to have it rust on you. If your bottle shows signs of rust, you can re-treat the surface with a citric acid bath. Citric acid is 100% environmentally friendly and doesn't require special equipment to handle. It's on the FDA's GRAS (generally regarded as safe) list, and costs about $1 for four ounces.
Dogs need exercise to burn calories, stimulate their minds, and keep healthy. Exercise also tends to help dogs avoid boredom, which can lead to destructive behaviors. Supervised fun and games will satisfy many of your pet's instinctual urges to dig, herd, chew, retrieve and chase.
