I'm thinking of working with a nutritionist but I need to wait at least a couple months as I just got slammed with a big vet bill.
Are there any supplements that you guys use that you would recommend? T is really fussy and I end up giving her things like bene bac because I can syringe it into her mouth and don't have to try to add it to her food.
Regardless of what you are feeding, you can't go wrong with giving probiotics. I use high potency (8 billion whatever it is) that is found in the refrigerated section of a health food or supplement store. Sabine also gives the option of using one in tablet form, but I thought that the refrigerated one might be more "alive". It supposedly tastes pretty good, too. Either way, I think it can only help with digestive issues, and won't hurt.
I second the idea of using Sabine, when you can afford it, even if you want to use commercial food. I hesitated for a while, thinking it seemed ridiculously extravagant to think my dog needed a canine nutrition specialist, especially considering that he is healthy, when there are many people in this very city who can't even afford to eat adequate diets. Then I figured that I am already serving the poor population in some ways, I already spend a fortune on toys and whatnot for my dog, and a healthy diet is more important than anything. Her rates are really reasonable, I think, and she is a good resource to have around for sure.
Also, and I'm pretty sure Sabine would agree, your dog is not going to die or suffer serious consequences if she eats a less than perfectly balanced diet for a short time, or temporarily, so don't worry too much if you can't consult w/her right away. Over time, though, it does matter a lot, so it is definitely worth the investment. Good luck!
