Matty is a very light eater. So keeping her weight in her acceptable range has been tough...I already see her eatting less, because of the heat...we live in Texas...What do you do to prevent your dogs from losing weight in the summer?
That is a good strategy too, dogs tend to wake up hungry, so if she naps in the early evening you can try about 830 or so at night.What do you currently feed? Kibble? RAW? And when? Does it help to feed her later in the evening when it starts to cool down?
And just a thought...when I had a horse that needed to gain weight due to being a hard keeper, I added a weight supplement to add a high quality fat to their diets. Is there such a thing for dogs that can be added without messing up the ratio of their proper nutrients?
