Direct answer: Most dog-scratched screen doors need either new screen mesh or a full screen door panel repair, not a whole new door. Start by checking whether the mesh is torn, the spline is pulled loose, or the frame is bent out of square.
Most likely: The most common fix is replacing torn screen door mesh after claws rip a corner, lower section, or latch side loose.
Pet damage usually looks worse than it is. If the aluminum frame is still straight and the door closes normally, this is often a screen-only repair. If the frame is twisted, the corners are spread, or the latch side no longer lines up, treat it like a damaged door assembly instead of a simple re-screen.
Don’t start with: Do not start by forcing the door straighter, slathering on glue, or ordering a whole replacement door before you know whether the frame is actually bent.
Claw holes, a long rip, or loose screen near the bottom half, but the frame looks straight and the latch still catches.
Start here: Start with the mesh and spline check. This is usually a re-screen job, not a door replacement.
One lower corner looks kicked out, the screen is loose there, and the frame does not sit flat in the opening.
Start here: Check the frame rails and corner joints before touching the screen. A bent frame can keep tearing new mesh.
The screen door rubs the threshold, misses the strike, or pops back open after the dog pushed on it.
Start here: Look for hinge-side looseness, a twisted frame, or latch-side damage before assuming the screen is the problem.
Scratches are concentrated low on the door, with dents or punctures in a lower panel or pet guard area.
Start here: Decide whether the damage is to removable screen mesh, a lower insert, or the door frame itself.
This is the usual result when a dog paws or jumps at the same spot. The frame stays usable, but the mesh opens up or frays around the claws.
Quick check: Press lightly around the tear. If the frame is straight and the screen is the only failed piece, the repair is usually limited to the mesh and spline.
A hard paw strike can yank the mesh edge loose without fully tearing it, especially at a corner or along the latch side.
Quick check: Look for a rubber cord partly out of the frame channel. If the groove is intact and the frame is not bent, re-screening usually fixes it.
When a dog hits the lower half hard, the thin frame can rack out of square. Then the door may drag, spring open, or keep loosening the screen.
Quick check: Compare the top and bottom gaps and sight down the latch edge. If one corner is kicked out or the door rocks when laid flat, the frame is damaged.
Sometimes the screen survives, but the hit loosens hinge screws or shifts the latch side enough to cause rubbing or poor closing.
Quick check: Open the door halfway and lift gently at the handle side. Extra play at the hinges or a shifted latch line points to hardware or frame movement.
You do not want to re-screen a door that is bent out of square. New mesh will not stay tight if the frame is twisted.
Next move: If the frame is straight and the door still fits the opening, move on to the screen material and spline. If the frame is twisted, a corner joint is split, or the door no longer fits the opening squarely, skip patching and plan for frame repair or door replacement.
What to conclude: Clean tears and loose spline point to a screen repair. A racked frame, dragging bottom rail, or bad latch alignment points to door assembly damage.
A lot of pet damage starts at the edge. If the spline channel is intact, the repair stays simple. If the groove is crushed or split, the door frame may not hold new mesh well.
Next move: If the groove is clean and continuous, the door is a good candidate for new screen mesh and fresh spline. If the groove is badly crushed, split, or widened in several spots, a re-screen may not hold for long and the frame itself becomes the real problem.
What to conclude: An intact groove supports a straightforward screen repair. Repeated edge failure or damaged channel usually means the frame took more force than the torn mesh suggests.
A dog can loosen hardware and rack the door at the same time. If the door drags or will not latch, you need to know whether that is from loose screws or a bent frame.
Next move: If tightening hardware restores smooth closing and the frame stays square, you can focus on the torn screen or lower insert. If the door still rubs, misses the latch, or springs out of alignment, the frame is likely bent or the corner joints have shifted.
Once you know whether the problem is mesh, spline retention, or a bent frame, the repair gets much more predictable.
Next move: If your chosen path matches the actual damage, the repair should hold and the door should close normally afterward. If you are still unsure whether the frame is straight enough to reuse, do not buy mesh first just because it is cheap.
A good repair is not just a neat-looking screen. The door has to open, close, latch, and stay square so the damage does not come right back.
A good result: If the screen stays tight and the door closes cleanly, the repair path was right.
If not: If the new screen loosens quickly or the door still sits crooked, stop spending time on the mesh and replace the damaged screen door panel.
What to conclude: A stable, square door confirms the damage was limited. Repeat loosening or poor fit means the frame was the real failure point all along.

A small temporary patch can keep bugs out for a short time, but it is usually not the best long-term fix. If the tear is from clawing, the surrounding mesh is often stretched and weak. A full re-screen holds better and looks cleaner.
Look for uneven gaps, a door that rocks on a flat surface, a lower corner kicked outward, or a latch side that no longer runs straight. If the door drags or misses the latch after the hit, frame damage is more likely than a simple screen tear.
Only if the frame is bent, the corners have spread, the latch side will not align, or the groove will not hold new spline. If the frame is still square, replacing the screen door mesh is usually enough.
The paw impact may have yanked the screen door spline out of the groove. That is common on older doors where the spline has dried out or shrunk. In that case, new mesh and fresh spline are usually the right fix.
If the frame is in good shape, a heavier pet-resistant screen can help in repeat-scratch areas. Just do not use tougher mesh as a substitute for fixing a bent frame or loose hardware first.
