Are Liver Treats Good for Dogs? Concerns with Liver Treats | Dr. Dobias (2024)

Is your dog at risk of liver treat toxicity?

Being a dog lover or a veterinarianrequiresbuilding a good rapport with dogs. Some dogs are social butterflies,while others take a little more convincing. Treats are one of the ways to connect with dogs and allow us to handle them and perform treatments when necessary.

For most dog lovers, treats are one of theways wetell our dogsthat we love them. Even complete strangers carry a few treats in their pockets to connect with dogs and their humans. I have always been a little conflicted about allowing others to give treats to my dogs. Poor quality Milk Bones and other treats are commonplace in stores, offices,and hotels, and most dogsare crazy about junk food.

“Just one” turns into many treats, and because I wanted to protect my previous dog Skai, and now Pax, from junk food, I developed a strategy of asking people not to give him treats. To prevent disappointment on both sides, I usually carried safer and healthier treats in my pocket to pass them onto the giver so thatheorshe could give them to Skai.

LIVER TREATS ARE THE MOST POPULAR BUT POTENTIALLY TOXIC TREAT

The purpose of this article is to warn against giving petstoo much of one treat that can be harmless in small amounts but toxic when it is frequently given - dehydrated liver.

Nutritionally, liver is a rich source of essential nutrients such as amino acids and fat. It isalso a rich source of some vitamins and minerals such as A, B6, B12, C, D, riboflavin, niacin, folate, pantothenic acid, iron, zinc, phosphorus, and selenium. Naturally, liver is arelatively small portion of acanine diet.

Functionally, the key role of the liver is to detox blood and the body, produce vitaminsand aminoacids, andmanage nutrients and energy resources for the rest of the body. The organ’s function is also to neutralize countless artificial and toxic chemicals from food and the environment, which is no easy task. This is why so many dog lovers see such positive results when they take their dogs through a semi-annual liver cleanse.

In the course of the last two decades, more people havetried to stay away from junky processed treats and go to single source meat or organ treats. This is one of the reasons why dehydrated liver has become one of the most popular items on the pet store shelves. Unfortunately, the popularity of liver treats has led to a new problem most dog lovers are unaware of: vitamin A hypervitaminosis, or so-called liver poisoning.

HOW DOES HYPERVITAMINOSIS HAPPEN?

The main cause of this condition is feeding large quantities of liver, which is a very rich source of vitamin A,amemberof the group of fat-soluble vitamins A, D, E, and K.Intheright amounts, Vitamin A is beneficial, butan overdose of Vitamin A can have a harmful effect because an excess of fat-soluble vitamins are much more difficult to eliminate than, for example, water-soluble vitamins B and C.

The reasons why liver treats, especially the dehydrated ones, put our dogs in danger of hypervitaminosisA are that they are greatly reduced in volume during dehydration, andthey contain ten times or more vitamin A then raw liver or cooked liver.

I have seen people givingtheirdogs large amounts of liver treats daily or onavery regular basis,which leads to problems.

THE SYMPTOMS OF HYPERVITAMINOSIS A

An excess of vitamin A causes disturbances in bone metabolism, increased bone resorption, and decreased bone production. This can lead to osteoporosis, spontaneous bone fractures, elevated blood calcium levels (hypercalcemia), and abnormal joint calcification.

Another symptom of hypervitaminosis A is a disturbance in absorption and function of other fat-soluble vitamins - D, E and K.

Under normal circ*mstances, dogs need vitamin A, and it isOK to give vitamin supplements with fermented vitamins. However, nature never counted on dogs getting large amounts of liver in the form of treats, and that is a big problem.

DIAGNOSIS OF LIVER TREAT TOXICITY - HYPERVITAMINOSIS A

In general, diagnosis is not a straightforward process. Radiographs, blood calcium, cholesterol, liver enzymes, and finally vitamin A (retinol) levels help to diagnose the condition.

TREATMENT AND PREVENTION OF LIVER TREAT TOXICITY

If your dog likes liver treats, do not give itmore than a couple of pieces a week, especially if the treats are dehydrated.

If you have been feeding yourdogalarge amount of dehydrated liver treats, and your dog does not show any symptoms:

Stop giving liver treats completely for at least three to six months

1. Perform a liver cleanse
2. Continue giving essentials such as Omega-3 oil, mineral-rich green superfood for additional gentle cleansing and providing your dog with necessary minerals and amino-acids to boost healthy metabolism.
3. After the first three months, you can introduce an organic fermented multi-vitamin for dogs to provide abalanced vitamin spectrum with carefully calibrated levels of fat-soluble vitamins.
4. Make dehydrated meat treats in place of liver. Generally, it is cheaper and safer to make them at home. If you buy treats in a pet store, always buy locally made products without chemicals or preservatives.

If your dog shows symptoms of possible hypervitaminosis A:

Implement steps one to four, PLUS

5. See your veterinarian and request radiographs and necessary blood tests.
6. If your dog’s diagnosis is confirmed, recheck radiographs in threetosix months post-diagnosis.
7. Introduce preventive measures and learn how to recognize symptoms of joint inflammation (arthritis), especially if your dog showed symptoms of joint calcification.
8. Share this article with others who may not be aware of the dangers of overfeeding liver treats.
