Am I tripping or what?

So I'm currently 5 months pregnant and me and my hubby are living with his mom temporarily until we get another place. Me and my hubby buy all the food in the house which I don't mind but what does make me mad is every time we buy hotdogs,lunchmeat, raviolis his mom literally feeds all off it to her dogs EVERY SINGLE TIME. On top of that my grandmother bought me a ninja for Christmas and his mom decided to use it to blend her dogs food up with. 
Would you be upset too? Or is it just my hormones or something. 
More info:She actually blends dry dog food with water and some powder stuff to make the dogs bigger or something.
