Today I gave the dogs (a lab mix and a chiwawa mix) the raw cow bones we got from Raley's yesterday for $2. I know that is probably a bit expensive for a pound of bone, but we just wanted to try it out. My chiwawa immediately started chewing on it, but my lab took a few minutes to warm up to it. I let them chew on it for about 25 minutes but my lab's gums started bleeding in the back of her mouth, so I took them away. Is it bad if there teeth start bleeding? Do their teeth and gums get tougher after a while? My lab doesn't mind you touching her while she is eating, but I expected my chiwawa to not like it so much. When I took her bone away she was growling, so I firmly said no and held her on her side. She is not aggressive any other time, not even with kibble, but she does not like her ''special'' treats to be touched. Is this a dominance issue that I should be working with her on? Well, I put their bones in a ziplock bag and put it in the freezer. I am going to leave tomorrow and won't be back until Sunday, so will the meat still be good if I freeze it until then? Sorry for all the questions, but I am just not sure. Thank you!
