that my puppy (8 week german/boxer cross) doesn't actually chew her food, she just swallows it.(Nutro Natural Choice for large breed puppies) She's always been fairly skinny (says the vet and most people that see her) but the other day she got into another dogs dish and ate all the iams adult dog food (more than I've ever seen her eat!), chewing it like a pro. After we offered her a piece of her food and she refused and then a treat and she still refused and then offered her a piece of the iams adult food and she went for it. Is this just because its a different food than the one she's eating now? Is it bad for them to just swallow their food and not chew? I used to have her on iams puppy food but she didn't seem to eat much of that either. Is there a good brand food out there that has larger kibbles or should i just stick with the same because I've already made the mistake of switching cause i thought she wasn't eating enough. I just want a plump, healthy puppy!
My dog and cat have both done that before. I started Frosty on homecooked food and he ate it so fast, I had to put dry in to make him slow down. It's because they're eating too fast and not taking enough time to chew. If he eats only once a day, or eats at really spaced apart times, make sure he gets fed more often to prevent hunger (so that he won't eat so fast). Make sure he eats right away in the morning. Try putting something like a rubber ball or kong toy (something sanitary that can be washed and won't take up too much space in the bowl) in the dish so he has to eat around it to slow him down. Don't necessarily change foods yet. Give it enough time and try enough things to see if they work.
a plump puppy isn't a healthy puppy, really. It's just a fat one. However, if your vet says your dog could do to gain some weight, increase the amount of food offered her at every meal. Stay with the same kibble for now, most dog food mnaufacturers don't increase the size of the kibble until it is adult dog food. Swapping foods can definitely make dogs more picky. Make sure you supervise her when she eats so you will know if she starts choking. As far as her eating the adult dog food in the other dish, I strongly suggest either feeding her in her crate and closing her in for meals, or picking up all the food within 20 minutes of putting it down. When you have 2 dogs, you really can't leave 2 bowls down at the same time all day long, especially when one has food in it. Dogs always go to the other dish and eat from it, and it's not a behavior you can really stop. It may start fights between your dogs later on, honestly, and it's so easy to avoid by picking up both food dishes after 'feeding time' is over.
