Well...some mothers are just not "so motherly" I have one. As soon as I got dogs, she said they were NOT welcome in her home, which is about 1/4 the value of my home, and she has indoor cats, and they both smoke indoors, but that is another story altogether. The dogs were just the excuse I needed to STOP going over there
But you are young, and living with your Mother, so you are going to have to be more diplomatic and work out a compromise.
Also, I started feeding my dogs a combination of wet/dry food when they were younger because I thought it would make it easier for them to chew. I believe once you start feeding them this way it will be hard to switch them over to just dry food. All 3 of mine love their Merrick, but only Darcy would eat it dry, and that is because I believe she was fed dry only (and not such a good quality) before she came to me. She thinks anything Mommy/Daddy gives her is just yummy, she is nothing like her finicky brothers!
