Sometimes I buy the 55 pound bags at the feed store and sometimes the 40 pound bags at TSC...
Always the black bags of sportsmix...
In the last 6 months or longer I have noticed I have to feed quite a bit more to keep my dogs at a good weight...they look good but it is a thorn in my side with this issue...I wormed my dogs several times and even swapped to a new wormer and no improvement...maybe I will swap back to diamond high energy if I can cut the feeding ration back...
I was meaning to post on this issue but this is a good time to do it...
My dogs were emaciated on sportmix. we had a bad summer last year and both my dogs got super skinny. I switched to diamond high energy and with in 3 weeks they were back to normal. i overfed them a little over the winter, and they got a bit overweight. as soon as school lets out for spring break, I'm running them like crazy.
