I changed Lexi over to Acana when she was able after I got her as she was on pedigree from the breeder. But I've discovered that she isn't chewing the acana just swallowing it. The acana is VERY hard and (although I aint going to try) I think I would have trouble biting through it. I dont know whether she doesn't chew it because she physically can't or because she can't as she still have the majority of her baby teeth used to chew and therefore she would chew as her adult teeth come through. She has VERY occasionally, twice thrown up and it's just been a small amount and the pieces of acana have come up whole. Now I've owned her for 5 months-ish and she has only ever done this twice and I'm not sure whether it is just because she has ran around or got herself all bothered too soon after eating in one of her mad runs around the house or something. But I don't know whether I should change her to something else. She seems to have a delicate throat and does cough at times (when drinking or pulling on lead). She does now occasionally have some naturediet trays that she gets for one meal a day every so often. Which she loves but I think it would be too expensive to order the trays in for every meal... :/ I really wanna keep her on acana and just give wet food as a little treat to keep her interested but I really don't know what to do. Perhaps she will get better at it with age or is it REALLY unhealthy for dogs to swallow it whole? Her stools at home or healthy enough if a little harder since she fully moved onto dry food rather than pedigree wet pouches, but they are different when she is out on a walk (weird!) so I don't think it is bothering her digestive system. Well REALLY sorry for the large rant but any advice would be welcome. Thanks for reading!
