200% incorrect. Vegan diets are carbohydrate-based. Carbohydrates are inflammatory, feed cancer (glucose), contribute to periodontal disease (leading to systemic organ failure, eg heart), cause insulin spikes leading to a multitude of other issues in the long-term (thyroid, liver, diabetes, heart disease) and also cause pancreatic problems due to extreme stress on the pancreas (secreting heavy loads of carb enzymes over a long period of time). The low moisture content coupled with high plant protein may also cause renal failure in the long term. The preservatives used may also be linked to cancer (BHA, BHT etc), and these diets also skew the omega3/6 ratio, causing further inflammation (linked to cancer again). They cause urine alkalinity leading to urinary problems such as crystals, blockages and UTI’s.
Brief into to dog anatomy/physiology:
- Stomach PH: Their highly acidic stomach is designed for eliminating harmful bacteria and breaking down bone into a gel-like substance. Humans have a much more alkaline stomach acid which is why we would struggle to digest raw bone.
-Digestive Enzymes: Higher level of proteases to break down animal protein. High bile load to help push through bacteria.
-Dental Anatomy: Sharp pointed teeth designed for ripping and tearing flesh and bones.Dogs do not chew their food as we do, they are wired to swallow chunks quickly as a basic survival instinct.
-Jaws: Dogs also have strong jaws that physically cannot move sideways (like your own can). This sideways grinding action is a feature that allows pre-digestion of plant material. Again, dogs rip off chunks and swallow them whole.
-Lack of Salivary Amylase: Omnivores have this for pre-digestion of carbohydrates. Dogs and cats do not. The canine pancreas secretes amylase as a backup, however this does not mean they should be fed a high carbohydrate diet every day for a lifetime. Processed food (incl vegan) is 40-70% carbohydrate.
-Lysozyme: Instead of amylase, dogs have lysozyme in their saliva which is an antibacterial. This may be useful for destroying any harmful bacteria in carrion/rotten food/feces, as well as wound cleaning.
-Gut length: The canine gut is short in length which is because flesh must be pushed through quickly. It does not need to sit and ferment, as this could allow bacteria to multiply to harmful levels. Note that plant eating animals have a long digestive tract and even multiple stomach chambers in order for plant material to be slowly broken down by the necessary enzymes.
-Nutrient profiles. Dogs have 0% biological requirement for carbohydrates. They gain every single essential nutrient from a prey based diet such as Whole Prey/Prey Model. Vegan diets are full of processed lab-made vitamins and minerals. Many vitamin pre-mixes are made in china and shipped to the country of manufacture.
All in all, dogs will survive on a high carbohydrate diet but it will cause systemic effects eventually. Similar to smoking, a junk food diet affects every dog differently and some may be affected more severely than others, and in different time spans. You can also expect high vet fees in the form of dental cleanings, dental surgeries and various health problem later on in life.
It is not recommended that you feed your pet the equivalent of a big mac for the entirety of its life. This is essentially what kibble and vegan diets are. Evolution has changed the appearance and even the behaviour of your dog, but their digestive system is still geared towards meat. Basically, you are paying money to have a company slowly kill your pet from the inside out.
