I would concur with the above answers.  If you are able to fill with wood putty and paint that would prove to be the most cost effective option.  If you would like to go further, determine the brand of the door and I'm sure you could find a replacement sash.  I am like you, I love my dog like my children, continue to be patient and show your bowser the love he deserves.

Consider, a new dog

There are a few options depending on the circumstances, if the dog has scratched the slab and depending on material, you'll need an entirely new slab. You have the option of painting over the scratch, but the odds of that peeling into the future are high. Our doors are steel and fibreglass, fibreglass would require an entirely new door slab to be installed if you wish to rid the problem for good. To surely rid the problem, the dog or puppy should be trained before repair unless you want to experience a fruitness endeavour. 

When dealing with a wooden door, their are a few DIY solutions like sanding, filling sanding again and painting/staining over. 

It looks like the pup teaches classes on how to be a beaver 101. Sanding, filling and matching the colour back would be the best option in this circumstance, or simply an entirely new replacement. 

It looks like the dog did a pretty good job on the door. Since the door is painted, you could sand the area down with some 150 grit sand paper. After it is sanded then you can apply some High performance wood filler or car bondo.

Apply a thin layer over the damaged area and allow it dry ( a few minutes or more depending on the amount of hardener you use). After it is dry, sand untill smooth and then apply a second layer if you need to and then sand smooth. After the area is the way you want it, prime it and paint it. 

Besides the painting suggested by Chad of Lonestar Painting which can truly makeover the appearance of a home, I suggest that the trees and shrubs be professionally trimmed and thinned out.  Application of weed control and fertilization of the lawn will provide a healthy and attractive canvas to your yard that can be supplemented with a dose of spring color annuals

A very quick and cost effective way to upgrade your homes exterior is a cleaning and color change. Pressure wash to clean it up and paint the shutters and front door.  They can remain the same color or pick a fresh new color.  You can also take any old fixtures that have faded over time and paint the metal with a fresh satin or gloss paint.  Same with metal railings or metal awnings. Possibly a one day job with big results. 

As a basement finishing company we're seeing a lot of granite for wet bars, lighter colors. Bathrooms and tile are often favoring gray. Brushed nickel and steel are the most common hardware and fixtures. Clean,simple, easy to mix up with rustic or modern decor.

We're still seeing a lot of demand for granite and/or quartz countertops.  With the quartz, people are doing more subtle patterns and a lot of marble looks (white with light veining or similar).  Cabinets seem to be following a gray/neutral/white color palette, with lots of clean lines.  We're still seeing stainless steel and brushed nickel for appliances and hardware, however we saw quite a bit of matte brass and gold tones at KBIS this year.  That seems to be making a comeback, but I think that might still depend on your area.  I think oil-rubbed bronze is probably on its way out, unless you're doing a rustic look.  Hope that helps!    

We have a painter that we use for all of our projects that involve staining or painting.  Painting Pro LLC.  One of the best we have seen and used for many years.  Let me know if you would like to contact him and I can send you his contact info.

CertaPro Painters- it’s a nationwide franchise. See their trucks all over. Never used them, but heard only good things so far. Good luck! … and let us know ;)

Are you looking solely for paint options or new exterior cladding options.  If the latter, go to everlastsiding.com.

Great product.

Try Shewin Williams Loxon XP which is for Masonry.  It lasts a very long time and no need to prime.

All of the premium coatings have been improving the last few years.  Our company uses Sherwin - Williams SuperPaint for the Body and Duration for the trim.  If you can afford duration for the whole house it could be worth the extra dollars. 

The newest thing is that paint has gotten expensive !

Thank you

If you currenlty have a house that is part brick and part siding (as opposed to all brick)... paint it.  If it's all brick with only wood trim accents, get a designers opinion.  If painting, be sure to use a premium bonding latex primer (like Gripper) and finish coat.  It'll make the house appear bigger and cleaner.  Most moisture will work its way through premium latex finishes and if it's enough moisture coming through the wall to deteriorate brick or cause your paint to peel, you've got a bigger issue to address.
