10 Best Hydrolyzed Protein Dog Foods and Treats Reviews

Protein hydrolysis is the chemical breakdown (degradation) of proteins to smaller units or hydrolysates that may be peptides or individual amino acids. It occurs by cleavage of peptic bonds that hold proteins together with the help of enzymes or chemicals.

Amino acids are the essential protein building blocks, while peptides are protein fragments made of 50 or fewer amino acids.

Why hydrolyzed dog foods

Food allergies are the third most common type of allergies that dogs suffer from after fleas and environmental allergies. It accounts for about 10% with animal protein sources, including beef, dairy products, fish, chicken, lamb, eggs, pork, and milk, the most common triggers.

However, corn, yeast, or wheat may trigger with glycoproteins they have blamed for the resultant hypersensitivities.

Not to be confused with food intolerance where your pet may have challenges digesting a particular food leading to digestive or gastric distress, bloating, gas, vomiting, diarrhea, nausea, and so on, food allergies occur as a result of an immune response.

Usually, when a dog eats something they are allergic to, their immunity mistakes the protein as an allergen (harmful or toxic foreign body), triggering an IgE antibody response that causes the various symptoms.

As noted, since proteins, including glycoproteins, are the primary sources of allergies, the main objective of protein hydrolysis is to breakdown the offending protein (one that triggers allergies) into smaller units or hydrolysate that a dogs immunity system can no longer recognize.

The hydrolyzed protein food is hypoallergenic, meaning that your dog can eat it with minimal chances of him suffering from allergies the protein source would have triggered.

Besides hydrolysis, other ways to manage pet food hypersensitivities include novel protein foods, limited ingredient foods as well as homemade diets. Your vet may recommend other hypoallergenic diets too.

Benefits and cons

Some of the benefits of hydrolyzed protein dog diets include the following:

• Reduce the chances of allergies without necessarily having to change the specific protein source, making it easy to provide complete and balanced nutrition.
• They are highly digestible, meaning your pet will absorb them more. Also, these diets will benefit dogs suffering from exocrine pancreatic insufficiency (EPI). Not that as affected ones they cannot secrete enough pancreatic enzymes needed for digestion.
• They will reduce the severity of symptoms of inflammatory bowel diseases (IBD) in these pets and benefit those suffering from severe enteritis.
• These foods will reduce instances of other allergies since they are hypoallergenic, and most use a single protein source.

Downside class

• They cost more. Like other prescribed diets, expect to spend more. On average, they are about 30% more expensive.
• Dont heal sensitivities and no long terms studies on possible side effects of unnaturally converted proteins. Your pets body will only not detect them.
• There is a decline of palatability as proteins are broken into smaller units and may end up bitter. Also, they may increase the intestines osmolarity. When it occurs, more water is drawn into the alimentary canal, leading to diarrhea.

Symptoms of dog food allergies

Some signs you canine friend may show in case of food allergies include the following:

• Dermatological manifestations They include skin lesions, irritated skin, and recurring ear infections. Recurring skin infections may also be witnessed. Besides ears, these signs may involve feet, perineal areas, axillary, face, or any part of the body.
