L-Carnitine supplement for increased  fitness and endurance for working and sporting dogs

 

A dog that takes part in high demand activities or indeed any long period of work calling for stamina and energy may find its natural system for producing the chemical L-Carnitine unable to keep up with demand.

L-Carnitine is an amino acid like compound produced naturally in the dog’s liver and kidneys which is then transported through the bloodstream to muscle cells. There it converts fat reserves to sugars whose metabolism then releases energy and stimulates muscle action and growth

A temporary deficit of L-Carnitine can lead to reduced energy and symptoms of fatigue and slow recovery time or the inability to develop stronger muscle power despite exercise and training

Ingredients

Stamina Plus contains 400mg/ml of L-Carnitine and 100mg/ml of Magnesium Aspartate Hydrochloride

Feeding

This liquid is given orally, preferably twice daily, to increase stamina and performance. It can be easily added to feed or introduced directly into the dog’s mouth.

It can be fed long-term as part of the dog’s maintenance regime or given for specific times when an extra challenging day is expected. In the latter case, be advised that the L-Carnitine present in Stamina Plus takes approximately 3 hours to reach its maximum benefit and stays at that level for a further 3 hours before gradually diminishing in its effect.

As with the other products, daily usage is calculated according to the dog’s bodyweight and the daily feeding level is 1-2 ml per 10kg (22lbs) of bodyweight twice daily.

Science

What is L-Carnitine?

L-Carnitine is small peptide/amino acid that is essential in all animals for the production of energy. Carnitine is needed by the body for the metabolism of fatty acids into energy in the cells. It helps the body utilize fat for conversion into energy while maintaining the lean muscle mass, which helps reduce the overall body fat. It may also help decrease the levels of cholesterol and lipids (fats) in the blood. 

Because L-Carnitine is essential in the process of converting fatty acids into energy a deficiency may result in increased fat storage, decreased performance, and, potentially, an increased risk of heart disease. A temporary deficit of L-Carnitine can lead to reduced energy and symptoms of fatigue and slow recovery time or the inability to develop stronger muscle power despite exercise and training. 

The natural source of L-Carnitine is fresh meat and milk, however manufactured pet foods frequently contain less than 5% of the L-Carnitine of fresh meat. With the vast majority of pets being fed on manufactured diets, supplies of L-Carnitine in the diet are often insufficient. Synthesis in the body occurs mostly in the liver. 

However skeletal and heart muscles, which use 95-98% of the supplies, cannot synthesise their own L-Carnitine and this explains why deficiency most commonly occurs in these tissues. 

The dog in particular is a species predisposed to a deficiency of L-Carnitine. This is because there is a high level of L-carnitine excretion via the urine and very little re-absorption through the renal tubules.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Great product
Style: Sport, Size: Large
This is a lifesaver. My lab will chase the ball all day and this saves the arms and shoulders. A little bit of a learning curve to use but I would definitely recommend

Labs love this!!!
Style: Sport, Size: Large
Our Lab LOVES everything about this thing! Recommend getting extra durable balls as the 1 included fell apart in 1 hour. I have a very energetic Lab retriever that we have to force to stop playing ball so he does not overheat. That & the force with which you can throw this ball did not help keeping it from splitting it in 2 in less than 1 hour. This is worth the money for the extra throwing power & distance but do invest in the ULTRA strong ball for dogs like retrievers! Also, be sure to order the correct SIZE OF BALL, specific to each different size of throwing wand. My fav thing about this item is #1 the joy my dog gets from the new challenge of racing to catch longer throws, & #2 I don't have to get my hands covered in dog slobber!! He has gotten to where he can almost put it in the cup himself so I won't waste time throwing the ball again! Man, I love that dog!!! ❤️
