2nd Try

Here are 2 pics fo my dog both with 15-55 nikon afs kit lens with pop up flash what do you think

 

I love your dog!
A little brighter background may help, the black fur blends into the background.

Gorgeous Dog. Like the photos (just a lil dark for me)

Try a slow syncro in Program

Or maybe a lil slower shuter speed with a flash in manual and just a nudge higher ISO.

Be prepared to use a table top tripod or a really steady hand..

Just my $0.02 nice photos though

 

nice pics...I would like the first one even better if the flash reflection wasn't so harsh on his eyes though

 

To diffuse the flash cut out a piece of milk jug and tape to your flash. This will help reduce the pet eye problems. Also as stated you need more of a color difference between your subject and background.

HTH

 

Rotties are one of my favorite dogs

I agree with what everyone else is saying. Also, I would try to blur the background a bit and see if that might help. You could lighten it while your at it.

I would also clean up the dust crumb's on the floor, and clone out that little tiny hair thing in picture #1, it's just a little distracting.

Nice shots though .. he sure looks like a cutie!!

 

I agree with the flash comments. But you did well to get so low, that's a great angle! Nice shots!

 

I agree as well about the flash...the first picture would be awesome without that reflection. Great job on the angles though!

 

Way to go with the low PoV. IMO, if possible on both, a much larger aperture, to blur the background.

The on-board flash is a problem. The background is competing with the subject. The vertical of the cabinet in #1 is awful. If rotated, the main subject suffers. Perhaps a tighter crop or another shot (w/o the flash).
