What to Look For in the Top Hill’s Science Diet Large Breed Dog Foods

Hill’s Science Diet for Large Breed Dogs is a fantastic option for larger dogs. However, the brand has an extensive dog food lineup. This can make choosing the best dog food from their line pretty difficult. After all, how do you decide which dog food will be best for your dog’s specific needs? When it comes to choosing the best option there are a few factors that you need to take into account. 

The most important factors to keep in mind when choosing between the top Hill’s Science Diet Large Breed dog foods include: 

  • Protein content 
  • Type of meat 
  • Necessary additives 

Let’s take a look at each of these factors in more detail below:

Protein Content

Your large breed dog needs to have a lot of protein in its diet. In fact, experts suggest that any dog food you get should have at least 30% protein. This is especially important for growing puppies, as it will benefit them later. Animal protein is also better as it contains more essential amino acids.

Type of Meat

The type of animal protein your dog’s food meat comes from may not matter, except in the case of allergies. The type of meat itself is, however, important. If your dog food contains a meat meal, this is the best as all the water content has been removed, making it have a high nutritious content. There is also whole meat which still has its water content and, while natural, might not be as highly nutritious as a meat meal. Finally, there are meat by-products that can also be of high quality but can be of questionable origin.

Necessary Additives

Large-breed dogs are prone to some serious health problems. One of these is hip dysplasia. This occurs more often with larger dogs because their joints tend to wear down faster because of the extra weight they carry. There are, however, additives like chondroitin and glucosamine, which are great for joint and bone health and should be included in any premium dog food. Others include omega-3 fatty acids and antioxidants.

The 2 Different Types of Hill’s Science Diet Large Breed Dog Foods

Hill’s Science Large Breed Dog Foods come in two different types. Each of these has its own pros and cons. It is helpful to know the differences between these two types of food options as one might be better for your dog than the other. 

Some of the most common pros and cons include: 

  • Wet food — Great for hydration as it has a high moisture content. Tends to be quite delicious for your pup and filled with nutritious ingredients. However, it must be refrigerated after being opened. Tends to be more expensive and has been linked to gum disease. 
  • Dry food — A less expensive option. Great for oral health as chewing helps prevent tartar buildup. Great for digestion and more varieties available. Provides less hydration. Has a high carb content.
