I have to feed one of my dogs Merricks and the other one Solid Gold. They're all great foods. It all depends on price & preference (yours ha)
I started feeding both of mine Merricks dry & wet (not too much wet or else it gives them the runs). But then I found out I have to feed C3PO Solid Gold Barking at the Moon because of his many many many allergies.
So Topaz still gets Merricks which I like
I feed Solid Gold Hund-N-Flocken (Lamb and Rice), I know that Annandael feeds her Basenji's Solid Gold MMillennia (Beef and Barley). I also when Reggie starts showing bordom in the Hund-N-Flocken I'll get him the Wolf King (Bison and Salmon) it's advertised for larger dogs but has almost identical nutritional ratings as the HNF. And I just ordered a bag of the SG Holistique Blendz (Fish and Oatmeal), I know he does like the Barking at the Moon (Salmon/Beef and Potatos), but its a little more pricey than the rest $52 for a 33lbs bag compared to $39 for HNF
Sahara love Merrick's Grammy's Pot Pie, dry and wet. I give her dry with a little water to make gravy and add about 1/2 cup of the wet. She eats it up and loves it better than all the rest I have tried. It is natural with no perservatives, and the company has been in business for many years, and it is family owned and all have their own furbabies. I also give her the other flavors of Merrick's for variety, mainly the wet.
