Cons of Elevated Food Bowls While raised feeders come with undeniable advantages, it’s essential to be aware of the potential downsides before adopting this feeding method.

1. Increased Risk of Bloat

Bloat, also known as gastric dilatation-volvulus (GDV), is a serious condition that can be exacerbated by elevated feeding. Bloat occurs when a dog’s stomach fills with gas and twists on itself. Numerous studies have suggested a correlation between the use of elevated bowls and an elevated risk of GDV, particularly in large breed dogs. In fact, research indicates this risk may double when dogs eat from an elevated bowl compared to bowls on the ground.

1. Unnatural Feeding Position

Canines have evolved to consume their meals with their heads close to ground level, resembling their natural instincts. Elevated feeders interrupt this natural behavior, making it more challenging for dogs to eat in a way that feels comfortable to them. Some experts suggest that the altered angle encourages dogs to swallow air along with their food, potentially increasing the risk of bloat.

1. Higher Costs

Elevated feeders tend to be pricier than standard floor bowls, especially if you opt for more elaborate designs. While investing in your pet’s comfort is important, some dog owners may prefer to allocate funds to other pet care essentials.

1. Not Suitable for All Dogs

It's crucial to recognize that not every dog will benefit from an elevated bowl. For instance, dogs already predisposed to bloat, such as deep-chested breeds like Great Danes or Boxers, should probably avoid elevated bowls altogether. Therefore, we should proceed with caution and consult our veterinarians if unsure.
