Hi, I have a Jack Russell x Shih Tzu (Ruby) is 4 years old. she gets groomed by a mobile dog was (we tried the groomers at the vet once but she was traumatised) Ruby has black nails and the groomer said they are harder to cut back because they can't spot the veins. the problem is that leaves ruby with really sharp nails and every time she sits on our laps are arms and legs look like we have been attacked by a mountain lion lol.. is there any way around this? or should we just deal with it? I don't want them to cut them too much so she isn't in pain and bleeding. any suggestions? thanks
