@breannexo My dog is a 12lb terrier mix girl and an extremely picky eater but so far Sundays is the only dog food she has been eating constantly. I still feed her some fresh veggies and fruits throughout the day as she loves them and when I run out of Sundays, I give her wet food for seniors (she's 11) for a couple days until I get my order.
It's true Sundays has been having a problem with delays on orders lately however I contacted them a few days ago about it and they made it right by offering a bag of Turkey recipe with one day shipping since they are out of Beef and Chicken. My dog doesn't like Turkey but somehow she's eating it fine this time so no major complains yet, otherwise I would be very disappointed and worried about having to switch her to a whole another food so in that way I sympathize with other commenters if they have not been able to get ahold of Sundays.
Also it is pricey but honestly not terrible if you have a tiny dog like mine or yours. I'm very low income and still able to make ends meet, however not doable if extremely low income. I will be unemployed in a few months so I am worried and thinking of switching her to something cheaper but honestly I don't think that will be possible so I'm gonna have to start saving up. Do wish it was more affordable but again I think the quality of food is justified to an extent.
In summary, I think Sundays has been a blessing for us as my picky eater with a sensitive stomach does well on it and it is easy to serve and clean up. I hated dry kibble because I believe it caused her to have tumors so I tried looking for something healthier after she got diagnosed with melanoma and read about mushrooms that are good for keeping cancer at bay and since feeding Sundays she has not had that melanoma spread or return so far it's been over a year! Obviously can't say it's just the food but I truly feel it contributed greatly and she has a lot of energy and loves long walks.
My dog as the extreme picky eater she is has been eating it daily. I'm not gonna lie and say that it was like that since day one, no she liked it for a few days (which is longer than any other food we've tried) and then would get tired of it but I made sure to try and be consistent and include a bit of variety with the veggies and fruits and occasional wet food and it's been working great now she will eat all her portions.
Additional comment: Regarding the crumbs issue I do agree that it bothered me a lot at the beginning spending so much money to have some of it become powder/crumbs however adding water to it to feed the powder/crumbs worked the other day so I am less worried about wastefulness now however it is a bit annoying but personally still worth it for me. Really hope Sundays is able to get all these shipping and crumble issues resolved soon though.
