Buyer’s Guide: How to Choose the Best Dog Bowl?

Your dog may be of any size, shape, height, and breed. For which, you may want to buy a dog bowl based on your dog’s eating habits and features. Then again, it should provide convenience to your dog while he eats.

Our team of experts at DogLovesBest have already tried and tested to select the best bowl for your canine but in order to get the perfect one for your pet consider the following factors that we have mentioned below.

• Size

Size is a feature that depends upon your dog’s size and breed. If your dog is small, there is no point in choosing a humongous bowl as you may find your dog splashing and swimming in the water instead of drinking it.

If your dog is large, then buying a small-sized bowl is of no use as he may not be able to put his snout in the bowl, resulting in unnecessary spillage of water.

The best is to buy a bowl as per your dog’s size and comfort. One or two sizes larger is more advisable, giving them enough space to drink water or eat food comfortably and at the same time, not dirtying your floor or carpet.

If you plan to store water for the entire day, it is advisable to get a large-sized bowl. But then again, you would not want the water to get stagnant.

For which it is advisable to get a dog water fountain, which keeps the water circulating, preventing the growth of germs and bacteria.

• Material

Dog Bowls are majorly available in 3 different materials, plastic, ceramic or stainless steel. A dog parent may choose to buy a feeder as per their dog’s convenience but also to keep in mind the safety of your pet.

Always look for quality and the brand before considering the material as a prime feature.

Plastic is light, easy to carry, light on your pocket, but should be of good quality, free of chemicals or made of BPA free material. In terms of ceramic, it is safe but very heavy and subject to break easily as it is too fragile.

The best material you can consider getting is stainless steel, not too heavy, easily portable, durable and non-porous. This keeps your water safe and free of dust and bacteria for a long time in the bowl.

• Type

There are various types of dog bowls available to suit every dog breed and as per the pet owner’s convenience.

If your dog is overweight, aged and suffers from joint pain, or has a good height, then getting an elevated dog water bowl is a good idea. Those ways, they would not have to bend always for having a sip or grabbing a kibble.

Collapsible dog bowls are good if your dog is a frequent traveler. If your dog loves taking a swim in the water bowl or enjoys dunking his face too much in the bowl, it is advisable to get a spill-proof dog bowl.

If your dog eats or drinks at the speed of light and chokes on it, slow feeder bowls work best. If you are not around during your dog’s mealtime, then automated dog bowls that take care of feeding your pet timely are the best buy.

• Ease of Cleaning

Most of the dog bowls are dishwasher safe, but this again depends on the material. Ceramic and stainless steel varieties possess a smooth surface and are easy to clean with warm water and mild soap. Some of them are even dishwasher safe.

Plastic bowls are easy to clean manually but not dishwasher safe. Most of the dog water bowls come with separate cleaning instructions which you can consider before cleaning the dog bowl.

• Non-Slip Base

If your dog has a habit of pushing, pulling, kicking or simply playing around with his bowl while eating, you must consider getting a bowl having a non-slip, rubber base.

This helps keep the dog bowl in place and avoid unnecessary spillage of contents. Your pooch does not have to keep shifting and moving around with the dish and can eat comfortably.

Why Do You Need a Dog Bowl?

One might wonder about the specific purpose a dog bowl may serve. But it has a lot to help with your pet’s eating and drinking habits.

Dog feeder bowls are available in a variety of shapes and sizes. A dog parent can choose the best one as per their dog’s size and breed.

Types of Dog Bowls

There is a wide range of dog bowls to choose from. They can majorly be classified into two types, based on material and based on structure.

The material determines the durability and the overall quality of the dog bowl whereas structure determines the convenience it can offer to your pet.

Based on Material

Speaking of the material, dog bowls are ideally available in 3 types: Plastic, Ceramic, and Metal.

• Plastic

These bowls are light in weight as well as a light on your pockets. Plastic dog bowls are easy to clean as they have a smooth surface and come in various shapes and designs which look attractive to your pet.

But then again, these bowls are not very durable and not dishwasher safe, unlike the other types.

It is also important to consider the quality and standards of plastic used in the dog bowl.

Ideally, plastic bowls should be free of BPA or any additional chemicals used in the manufacturing process as these chemicals may prevent degradation of the material but prove to be extremely harmful to your pet with long-term use.

• Ceramic

Ceramic dog bowls are safer and better, but heavier and costlier. Ceramic bowls have zero chemicals and help store your pet’s water for a long time over the day. But then again, these cannot be carried around, as the material is heavy and easily breakable.

If your pet is impatient, extremely agile, chirpy, enthusiastic and moves about anxiously while he feeds, then getting a ceramic feeder would not be a great idea as your pet can break it easily.

But then again, ceramic dog bowls have a smooth surface, are easy to clean and maintain, and keep your dog’s food fresh for hours.

• Stainless Steel/Metal

One of the most durable and strongest types, these dog bowls are resistant to kicking, pushing or any damage that your dog can cause to its food bowl. Metal is non-breakable and non-porous with a smooth surface. Being non-porous, avoids the formation and entry of micro-organisms in food, keeping it safe and hygienic for hours of being untouched in the food bowl.

Metal dog bowls are also usually dishwasher safe and easy to clean with mild soap and warm water. Make sure to choose a good quality stainless steel material.

Metal bowls are also available as alloys which is a mixture of various metals. They are also light-weighted and are portable, long-lasting and convenient to use.

Based on Structure

We have classified different dog bowls based on their structure and how convenient it would be for your pet to use.

Each dog has a different size, belongs to a different breed and hence would have its own challenges while feeding. Some would be short, overweight, tall or aged.

Some dogs may have different feeding habits and patterns. Based on this, these dog bowls are designed suitably so that your pet can feed comfortably without causing you any hassles.

• Elevated

This is the best investment for adult and aged dogs. For dogs who have joint pains, arthritic problems, or for those breeds which are tall and find it difficult to bend, elevated dog bowls are the perfect solution. These bowls can be ideally placed on a stand which has a good height and separate slots for placing the bowls.

This raised type of food and water bowl works as a good water and food station for your pet and is designed in such a way, that prevents spillage of contents from the bowl.

It usually comes as a package of separate bowls for water and food, avoiding the mess and keeping the food bowl dry and the water bowl clean.

• Slow Feeder

Does your dog gulp down on his food too quickly? Does he lick his bowl clean in a jiffy when you serve him food? Does your dog not relish his food? Or does he choke on his food and throws up whenever he eats or drinks water?

If you relate to any of the above situations as a dog parent, then what you need is a slow feeder dog bowl. These bowls are specifically designed in such a way, that your dog is forced to eat slowly, thereby preventing gulping and choking of food.

These dog bowls have various grooves and ridges, or usually have an uneven surface that automatically reduces your dog’s eating speed.

This way your dog inculcates a habit of eating slowly, ensuring proper digestion and absorption of food and nutrients in the long run.

Slow feeder bowls are available in different designs and shapes, you can choose as per your dog’s feeding and eating habits.

• Automated

It is not always possible to be at your dog’s beck and call, especially when it comes to their feeding timetable. Your dog may follow a fixed eating pattern and may have a fixed food proportion.

So, if it is not possible for you to feed him from time to time, automated dog bowls do the task for you.

Automated dog bowls offer the convenience of operating from anywhere through your phone or laptop.

So if you are away from your pet, and not around during your dog’s mealtime, your dog can have his food served at the right time, in the right quantities just at the press of a button. Simple.

They either have inbuilt sensors or can be operated through your phone or any device to dispense your dog’s food at suitable time intervals as per your dog’s eating schedule.

You can also fix the time beforehand on the automated device, so it dispenses food automatically at the allotted time.

• Collapsible

If having a dog bowl in your house floor can get risky as it is subject to spilling or breaking, why not have a bowl conducive to such cases? The best collapsible dog bowls are foldable, easy to store, and very compact and light-weighed.

These dog bowls are usually made of silicone or rubber and can easily fit in your bag. You can carry it with you, open it as per requirement and then fold it back to its original shape once used. It is easy to assemble. Simply open it when your dog is thirsty or hungry and fold it back when your dog is done feeding.

This offers the convenience of carrying the dog bowl with you, especially when you go tripping with your pet while it is also convenient for pets who are habituated to eating in a dog bowl.

• Spill-Proof

If your dog’s a sloppy and messy eater and likes to dig inside his food or water bowl while eating food or drinking water, then spill-proof dog bowls are the best buy.

Firstly, they have a sloped design, which is specially designed so that your dog does not spill or drop food and water here and there. This prevents their feeding area from getting messy and watery, which works best for any dog owner and reduces their efforts of cleaning around and about the house and floor.
