The best starting strategy in Rescue Dogs vs Aliens is to build two upgraded Bork Cannons at the first major choke point, saving your remaining Kibble Coins for a Slobber Tower by Wave 4 to handle Scuttler rushes. This disciplined opening prioritizes high-impact, single-target damage and crowd control over spamming cheap, ineffective towers, ensuring you have the economic foundation and firepower to survive the crucial early game and push into the mid-game with a significant advantage.
Many new players fall into the trap of building too many different types of towers too quickly, spreading their resources thin. This guide provides a step-by-step build order, placement map, and economic plan that has been tested and proven to crush the first 10 waves on any of the starting maps, from The Kennel Run to Fido's Field. Master this opening, and you'll master the game.
Your First 5 Waves: The Unbeatable Opening
Your initial 650 Kibble Coins are the most important funds you'll spend. Wasting them means a restart. This build order is designed for maximum efficiency, giving you a rock-solid defense by the time the first challenging enemy, the Armored Grunt, appears in Wave 5.
Wave 1: The First Bork Cannon
Immediately pause the game. Identify the longest straight path or the first tight corner after the alien spawn point. Place your first Bork Cannon (100 KC) here. You want to maximize the time it can fire on a single target. Its high damage and decent fire rate make it the perfect workhorse for picking off the slow-moving Blobs that populate the first two waves. Do not build anything else. Start the wave and let it run.
Wave 2-3: Upgrade and Save
After Wave 1, you should have enough to upgrade your Bork Cannon to Level 2 (125 KC). Do this immediately. The DPS boost is substantial and will be critical for the increased enemy count in Wave 3. For the rest of Wave 2 and all of Wave 3, your only job is to save Kibble Coins. Resist the urge to build another tower. Your upgraded cannon can handle these waves alone. Your goal is to bank enough currency for the next essential purchase.
Wave 4: Placing the Slobber Tower
Wave 4 introduces the Scuttlers—fast, low-health aliens that travel in packs. A single Bork Cannon, even upgraded, will struggle to hit them all before they leak. This is where your savings pay off. Just before the wave begins, place a Slobber Tower (200 KC) about one tower-radius behind your Bork Cannon. Its area-of-effect slowing goo will cause the Scuttlers to bunch up, allowing your cannon to eliminate them efficiently. This cannon-and-slower combination is the foundational defensive tactic in the game.
Wave 5: The Second Cannon and First Grunt
You are now facing your first real test: the Armored Grunt. This slow-moving tank can absorb a huge amount of punishment. Before the wave starts, use your accumulated coins to build a second Bork Cannon (100 KC) next to your first one. Both cannons, firing on a slowed Grunt, will bring it down before it gets halfway through your kill zone. With two cannons and a Slobber Tower, you have a stable core defense that will carry you through to Wave 10.

Mastering Your Economy: Kibble Coins and Upgrades
Rescue Dogs vs Aliens is as much an economic game as it is a strategy game. Every Kibble Coin you spend is a choice, and making the right ones early on creates a snowball effect that leads to victory. The core economic principle is to prioritize upgrading a few well-placed towers over building many weak ones.
A Level 2 tower is almost always more cost-effective than two Level 1 towers. It has better stats per coin spent and, crucially, only takes up one build slot. Build slots are a finite, precious resource, and filling them with weak towers is a path to being overwhelmed in later waves.
Consider the raw numbers for your workhorse, the Bork Cannon:
| Level | Cost (KC) | Upgrade Cost (KC) | Damage | Rate of Fire | DPS | DPS per 100 KC | Footprint |
|---|---|---|---|---|---|---|---|
| 1 | 100 | - | 10 | 1.0/s | 10 | 10.0 | 1 Slot |
| 2 | 225 | 125 | 22 | 1.1/s | 24.2 | 10.7 | 1 Slot |
| 3 | 475 | 250 | 45 | 1.2/s | 54.0 | 11.3 | 1 Slot |
As the table shows, the DPS per coin invested increases with each level. While two Level 1 Bork Cannons provide 20 DPS for 200 KC, a single Level 2 provides 24.2 DPS for just 225 KC while saving a build slot. This efficiency is the key. Your upgrade priority after establishing your core defense should be getting one Bork Cannon to Level 3, then your Slobber Tower to Level 2 for a wider slow radius.
Advanced Tower Placement: Choke Points and Kill Boxes
Where you build is just as important as what you build. Every map has optimal locations that force aliens into kill boxes—areas where multiple towers can attack them simultaneously for an extended period. Your goal is to create these zones.
Identifying the "Golden Triangle"
On most early maps like The Kennel Run, look for a U-bend or S-curve in the alien path. The land inside the curve is the most powerful building area on the map. You can often find a spot where three tower locations form a triangle that covers the path on two or even three sides. This is the "Golden Triangle." Your first three towers—two Bork Cannons and one Slobber Tower—should always form this core. Placing them here ensures that as aliens round the bend, they are slowed and constantly under fire from multiple angles.

Layering Fields of Fire
Never place all your towers in a single straight line. Stagger them. Your Slobber Tower should be placed first in the sequence, forcing aliens to slow down as they enter the kill zone. Your primary single-target damage dealers, like Bork Cannons, should be placed directly after, where they have the longest, clearest shot at the slowed enemies. This ensures your damage is concentrated and not wasted on targets that are about to leave your range.
By Wave 8 or 9, you should be adding a third Bork Cannon or starting to save for a powerful area-of-effect tower like the Puddle Plower. Place this new tower so its firing radius overlaps with your existing cannons. This layered approach means no alien can pass through without taking sustained, focused damage from your entire defensive array.
Know Your Enemy: Alien Types in Waves 1-10
Beating the aliens requires understanding their behavior. The first 10 waves introduce three fundamental enemy types, each designed to test a different aspect of your defense. Recognizing them on sight and knowing their weakness is non-negotiable.
| Alien Type | Health | Speed | Weakness | First Appears | Strategic Counter |
|---|---|---|---|---|---|
| Blob | Low | Slow | N/A | Wave 1 | A single Bork Cannon is sufficient. |
| Scuttler | Very Low | Very Fast | Grouping | Wave 4 | Slobber Tower to bunch them up for cannons. |
| Armored Grunt | High | Slow | Focused Fire | Wave 5 | Two or more Bork Cannons firing on the same target. |
The biggest mistake players make is underestimating the Scuttlers in Wave 4. They ignore the need for a slowing tower and find their single cannon overwhelmed as the fast-moving aliens zip past. The second common failure is not having enough single-target DPS for the Armored Grunt in Wave 5. The build order in this guide is specifically designed to counter these two pivotal threats head-on.

Frequently Asked Questions (FAQ)
What's the absolute best first tower to build in Rescue Dogs vs Aliens?
The Bork Cannon is unequivocally the best starting tower. It costs only 100 Kibble Coins and provides efficient, high-impact single-target damage that is perfect for handling the slow, single-file enemies of the first three waves.
Should I upgrade towers or build new ones early on?
Upgrade first. Getting your initial Bork Cannon to Level 2 before Wave 3 is far more cost-effective than building a second Level 1 tower. This maximizes your damage output while conserving precious build slots for later in the game.
How do I deal with the fast Scuttler aliens in Wave 4?
The key is crowd control. You must have a Slobber Tower built before Wave 4 begins. Place it just behind your main damage tower. Its slowing effect will clump the fast Scuttlers together, making them easy targets for your Bork Cannon and preventing them from overwhelming your defenses.
Your Path to Victory
Surviving the opening of Rescue Dogs vs Aliens isn't about complex strategies or unlocking ultimate towers. It's about discipline and efficiency. By following the build order of Bork Cannon > Upgrade > Slobber Tower > Second Bork Cannon, you create a defensive core that is both economically sound and tactically dominant. You'll enter the mid-game with a healthy bank of Kibble Coins and a kill box that can handle anything the aliens throw at you. Now go save those dogs.
