Automatic Feeder for Rottweiler Puppy to Adult

An 18-month Rottweiler is right at that changeover point — puppy feeding schedules and portion sizes no longer apply, and getting the new amounts dialled in accurately really matters for a large breed. The most important things in a feeder for this situation are portion accuracy, ease of cleaning, and mechanical reliability — cheap feeders jam, dispense inconsistent amounts, and are often a nightmare to sanitise, which becomes a real hygiene problem. Before I point you in the right direction: is this feeder just for your Rottweiler, and what's the main reason you're using one — work schedule, travel, or keeping the portions consistent during this transition?

That's a sensible approach — overfeeding during this window is one of the main reasons large-breed dogs carry excess weight into adulthood, and a Rottweiler's joints will thank you for keeping him lean. Since you're home and it's about precision rather than remote operation, I'd skip the app-heavy models that charge for features you won't use. Can you tell me roughly how much he's eating per meal right now, and whether you're on kibble or wet food? Also, is he a fast eater — does he tend to gulp?

Good — dry kibble makes this much more straightforward, and the portion sizes you're describing are well within range for a reliable automatic feeder. For a single large-breed dog where accuracy and hygiene are the priorities, I'd go with the PetSafe Healthy Pet Simply Feed. It handles portions from 5ml up to 240ml per meal, uses a rotating drum mechanism that's genuinely consistent with kibble (not just a flap that jams), and the bowl and parts that contact food are dishwasher safe. You can programme two meals a day at whatever times suit you, and there's a slow-feed dispensing mode that trickles the portion out over 15 minutes — which directly addresses the gulping issue your vet flagged, without needing a separate slow feeder bowl. As your Rottweiler settles into adult portions, you just adjust the portion setting — no need to buy anything new. It's available on Amazon UK for around £55–65 and has a strong reliability track record for larger portion sizes.

Yes — the PetSafe Simply Feed uses a conveyor-style drum rather than a gravity chute, so large-breed kibble pieces move through cleanly without bridging or jamming, which is a common failure point on cheaper models. The one thing to avoid is anything with very irregular shapes or very high fat content that could leave residue in the drum — standard large-breed dry kibble is fine. Set the slow-feed mode, start his adult food transition gradually over about two weeks by mixing ratios, and use the feeder to lock in the new portion size once you've settled on it. That way the feeder is doing the measuring, not guesswork at the scoop.

Good choice for this specific situation — the slow-feed mode alone is worth it for a dog that gulps. Once he's been on the adult schedule for a few weeks and his weight is stable, you can fine-tune the portion setting up or down in small increments. Keep an eye on his waist definition rather than just the scales — that's the best indicator with large breeds. Hope the transition goes smoothly.
