Dog Fence & Pet Fence: Best Aluminum Styles for Dogs
Small dogs, puppies, and cats can slip right through a standard 4-inch picket gap. These aluminum fence styles have the tighter picket spacing needed to keep pets safely contained.
Quick Answer
Standard aluminum fence panels have about 4" between pickets — wide enough for puppies, toy breeds, and cats to squeeze through. Puppy picket (or pet picket) panels close that gap to roughly 1-1/2 to 2 inches by adding a second set of shorter pickets between the main pickets. Our pet-friendly styles include Athens, Avalon, Berkley, Buford, Chamblee, Cobb, Dublin, and Dunwoody.
What Makes a Fence “Pet Friendly”?
A standard aluminum fence panel has vertical pickets spaced roughly 4 inches apart. That's narrow enough to keep children and larger dogs contained, but small dogs, puppies, and cats can easily fit through — especially along the bottom of the fence where the gap is most accessible. There are two ways to solve this:
A puppy picket fence (also called a pet picket) adds a second row of shorter vertical pickets between the main pickets, but only along the bottom sectionof the panel. This tightens the spacing to about 1-1/2 to 2 inches right where pets try to slip through, while keeping the standard aluminum-fence look above dog-eye level. Styles like Avalon and Cobb use this configuration.
A double picket fence runs the extra pickets the full height of the panel, from top to bottom, creating tight spacing throughout. This gives maximum security and a denser visual look. Styles like Athens, Buford, Chamblee, and Dunwoody use double picket construction.
Both configurations result in roughly 1-1/2 to 2 inches between pickets — small enough to contain even toy breeds, puppies, and kittens.

Choosing the Right Height for Your Dog
Picket spacing keeps small pets from squeezing through — fence height keeps athletic dogs from jumping over. Match your height to your dog's size and jumping ability:
3ft Fence
Toy breeds, senior dogs, small dogs that don't jump. Not suitable for active dogs.
4ft Fence
Most small and medium breeds. Our most popular height for household dogs.
5ft+ Fence
Large, athletic, or working breeds — German Shepherds, Huskies, Malinois, etc.
Not sure? Go taller.
Dogs are better jumpers than most owners realize. If your dog is athletic, young, or has a habit of jumping on things, size up to a 5ft fence. It's a lot cheaper than replacing a fence a year later because your dog keeps clearing it.

Why Aluminum Is the Best Pet Fence Material
No Chew Damage
Unlike wood fencing, aluminum can't be chewed or scratched through by dogs. The smooth powder-coated surface offers nothing for teeth to grip, so even persistent chewers can't damage the fence.
No Sharp Edges
Chain-link fencing has sharp wire ends that can cut pets. Aluminum pickets are smooth and rounded, with no wire barbs or exposed metal ends at dog level.
Non-Toxic Finish
Our TGIC powder coating is non-toxic and pet-safe. There are no chemical treatments, preservatives, or toxic coatings that could harm pets who lick or chew on the fence.
Visibility & Airflow
Open picket designs let dogs see and hear their surroundings, reducing anxiety and boredom compared to solid privacy fences. Airflow also keeps the yard cooler in summer.

Frequently Asked Questions
What is a puppy picket fence?
A puppy picket fence (also called a pet fence or puppy panel) has tighter-than-standard vertical spacing between pickets to prevent small dogs, puppies, and cats from slipping through. Standard aluminum fence panels have roughly 4-inch picket spacing, while puppy picket panels reduce that to about 1-1/2 to 2 inches — small enough to contain even toy breeds and young puppies.
Which aluminum fence styles are best for dogs?
The best aluminum fence styles for dogs are those with double picket or puppy picket construction — these reduce the standard 4-inch picket gap to about 1-1/2 to 2 inches, preventing small dogs and puppies from slipping through. Double picket styles run the tight spacing the full height of the panel. Puppy picket styles add tight spacing only along the bottom section where pets are most likely to escape. See the pet-friendly styles table on this page for the full list from our catalog.
What is the best fence for small dogs?
The best fence for small dogs combines tight picket spacing with appropriate height. A puppy picket or double picket aluminum fence at 4ft height works well for most small breeds. The tight 1-1/2 to 2 inch picket spacing prevents small dogs from squeezing through, and 4ft is high enough to contain non-jumping small breeds. For small dogs that are athletic jumpers or escape artists, size up to 5ft. Aluminum is ideal because it has no sharp edges, no toxic coatings, and cannot be chewed through.
How tall should a fence be for dogs?
Fence height depends on your dog's breed and jumping ability. For small dogs and most medium breeds, a 4ft fence is typically sufficient. For large breeds, athletic dogs, or known jumpers, a 5ft or 6ft fence is recommended. Athletic breeds like German Shepherds, Huskies, and Malinois can clear a 4ft fence easily — plan for 5ft minimum.
Will a puppy fit through a standard 4-inch picket gap?
Yes. Small breed puppies and adult toy breeds can easily squeeze through a 4-inch gap. Chihuahuas, Yorkies, Dachshunds, Pomeranians, and similar breeds need the tighter picket spacing of a puppy picket or pet fence. Cats can also slip through standard pickets, so pet picket panels are a good choice for multi-pet households.
Is aluminum fencing safe for pets?
Yes. Aluminum fencing is one of the safest materials for containing pets. It has no splinters like wood, no sharp wire ends like chain-link, and no toxic chemical treatments. The powder-coated finish is pet-safe, and the smooth pickets cannot be chewed or damaged by most dogs. There are no points, barbs, or hazards at dog level.
