On Monday, she spends 4 poodles * 2 hours = <<4*2=8>>8 hours walking poodles.
On Monday, she spends 2 Chihuahuas * 1 hour = <<2*1=2>>2 hours walking Chihuahuas.
On Tuesday, she spends 2 Chihuahuas * 1 hour = <<2*1=2>>2 hours walking Chihuahuas.
On Wednesday, she spends 4 Labradors * 3 hours = <<4*3=12>>12 hours walking Labradors.
Over the week, this is a total of 8 + 2 + 2 + 12 = <<8+2+2+12=24>>24 hours spent dog-walking.
This means she still has 32 maximum hours – 24 used hours = <<32-24=8>>8 hours available for dog-walking.
Therefore, she can walk 8 hours / 2 hours per poodle = <<8/2=4>>4 poodles on Tuesday.
