bloggy nugget dub-style

so since yesterday dublin has been limping... when he runs, he doesn't limp... if i touch his leg he doesn't cry... he jumps up and onto the bed and down off it without making a sound... but when he walks across the room he limps... i'm a little weirded out... he doesn't seem to be in pain, but he's definitely limping... now, he DOES need to get groomed, so i'm thinking maybe his nails are too long and when he walks they feel weird? hopefully that's the case, because then by tomorrow it would be all fixed... i just hope there's nothing really wrong with the little guy...
