When choosing an automatic dog feeder, prioritize capacity, anti-jam technology, and ease of cleaning. Look for durable, food-safe materials like BPA-free plastic or stainless steel, a secure and tamper-resistant design, and a reliable power source with a battery backup option. Additional features like customizable meal sizes and times, and integrated cameras for remote monitoring, can also enhance functionality.

Core features

• Capacity: Select a hopper size that holds enough food for your dog's needs to minimize the frequency of refills.
• Anti-jam technology: This ensures the feeder reliably dispenses food without getting stuck, which is crucial for consistent feeding.
• Ease of cleaning: Look for models with removable, dishwasher-safe bowls and components that are easy to disassemble for regular cleaning to maintain hygiene.
• Durable and safe materials: Opt for high-quality, non-toxic materials like BPA-free plastic or stainless steel to ensure your dog's safety and the feeder's longevity.
• Power source: A stable power source is essential. A battery backup is a critical feature to ensure feeding continues even if the power goes out. 

Design and security

• Tamper-resistant lid: This prevents your dog from accessing the food storage, keeping the food fresh and secure.
• Stability: A secure, tip-resistant design prevents spills and keeps the feeder in place.
• Food compatibility: Make sure the feeder is compatible with your dog's specific food type (kibble size, etc.). 

Advanced features

• Customization: Many feeders allow for scheduled meal times and portion sizes, helping with portion control and maintaining a regular feeding schedule.
• Integrated camera: Some models include a camera with features like night vision and two-way audio, allowing you to monitor your pet, check their eating habits, and even dispense treats remotely.
• Smart connectivity: Wi-Fi-enabled feeders can offer advanced scheduling and notifications through a smartphone app.
