Most 2-in-1 collars top out at 100-120 lbs. The Aikeep goes to 120 lbs. The Delupet stops at 100 lbs.
The Colofrog goes to 150 lbs — the highest capacity in the 2-in-1 category.
That’s a big deal if you own a giant breed. Great Danes, Mastiffs, Saint Bernards — these dogs are often excluded from standard collars. The Colofrog is one of the few 2-in-1 options that actually fits them.
But the 150 lb capacity isn’t the only standout feature. The remote battery lasts 50 days — best in class. The collar itself has a 35-day battery. And with 2,652 reviews and a 4.4-star rating, it’s the most established 2-in-1 collar in this comparison.
I’m Dr. Allona Jackson, DVM. In this Colofrog Dog Collar review, I’ll break down both modes, compare the Colofrog to the Aikeep and Delupet, examine the standout features, and give you my honest verdict.

Key Features Deep Dive
150 lb Weight Capacity — Best in Class for Giant Breeds
This is Colofrog’s standout feature.
What it means: The collar fits dogs up to 150 lbs — higher than Delupet (100 lbs) and Aikeep (120 lbs).
Why this matters: Giant breed owners — Great Danes, Mastiffs, Saint Bernards — are often excluded from standard collars. Most 2-in-1 collars top out at 100-120 lbs. The Colofrog is one of the few that fits them.
Real-world use: Works for dogs from 10 lbs (small Frenchie) to 150 lbs (giant Great Dane).
Dr. Jackson’s take: *”The 150 lb capacity is Colofrog’s standout feature. Most 2-in-1 collars top out at 100-120 lbs. If you have a giant breed over 120 lbs, your options are very limited. The Colofrog is one of the few that fits them. This alone makes it worth considering for large dog owners.”*
50-Day Remote Battery — Best in Class
The Colofrog offers exceptional battery life.
| Component | Battery Life | Charge Time |
|---|---|---|
| Remote | 50 days | 2 hours |
| Collar | 35 days | 2 hours |
Compared to competitors:
- Delupet: 45 days remote, 35 days collar
- Aikeep: 30+ days remote, 15+ days collar
Dr. Jackson’s take: *”50 days on the remote is exceptional — charge it every other month. The 35-day collar battery is also excellent. This is the best battery life in the 2-in-1 category. If you’re forgetful about charging, this is a real advantage.”*
2-in-1 Design — Can Work Without Remote
The Colofrog can function as a bark collar even without the remote.
Bark Control Mode: Automatic bark detection — no remote needed. The collar works independently.
Dog Training Mode: Remote control required. Use for obedience and recall.
All Mode: Both active simultaneously.
Dr. Jackson’s take: *”Same 2-in-1 concept as Aikeep and Delupet. The ability to use bark control mode without the remote is the key feature here. You don’t need to carry the remote for the collar to work. Leave it on your dog during the day and let the bark collar do its job automatically.”*
Smart Bark Detection Chip (False Trigger Prevention)
The Colofrog uses an advanced chip to accurately identify your dog’s barking.
What it does: Distinguishes between actual barking and vocal cord vibration (whining, grumbling) — plus filters out ambient noise.
Why it matters: Prevents false triggers from other dogs barking, loud noises, or your dog shaking.
2 working states:
- Beep + Vibration (gentle, no shock)
- Beep + Vibration + Safe Shock (includes static stimulation)
Dr. Jackson’s take: *”Similar to Delupet’s AI chip. False triggers are the #1 complaint about bark collars — owners hate when the collar activates because another dog barked. The Colofrog’s chip should reduce those frustrating moments. The two working states give you flexibility: start with vibration-only, add shock only if needed.”*
5 Sensitivity Levels (Bark Collar Mode)
The bark collar has 5 adjustable sensitivity levels.
| Level | Sensitivity | Best For |
|---|---|---|
| 1 | Most sensitive | Quiet barkers, small dogs with high-pitched barks |
| 2 | High sensitivity | Most small to medium dogs |
| 3 | Medium sensitivity | Good starting point |
| 4 | Low sensitivity | Large dogs with deep barks |
| 5 | Least sensitive | Very large dogs, dogs who bark loudly |
Dr. Jackson’s take: *”Standard 5-level sensitivity — matches Aikeep and Delupet. Start at level 3 and adjust based on your dog’s barking volume. Small dogs with high-pitched barks may need level 1-2. Giant breeds with deep barks may need level 4-5.”*
3 Training Functions with 99 Levels
The remote training mode offers three correction types with excellent granularity.
| Mode | Levels | Best For |
|---|---|---|
| Beep | 1-8 | Sound-only warning; gentle reminder |
| Vibration | 1-16 | Gentle physical cue |
| Safe Shock | 1-99 | Precise static stimulation; fine-tuned control |
Dr. Jackson’s take: *”Same excellent 99 levels as Aikeep and Delupet. The 16 vibration levels are better than Delupet’s 3 — you have more fine-tuning ability. This matches Aikeep’s vibration range.”*
3300FT Range
The Colofrog offers up to 3,300 feet of range.
Real-world use:
- Parks: Full coverage of most dog parks
- Backyards: Plenty of range
- Open fields: Over half a mile
Compared to Delupet: Delupet offers 4,500 ft (longer), but 3,300 ft is still excellent.
Dr. Jackson’s take: “3,300 ft is plenty for most owners — over half a mile. The Delupet’s 4,500 ft is longer, but most people won’t need the extra 1,200 ft. Unless you have a massive rural property or hunt with your dog, 3,300 ft is sufficient.”
IP67 Waterproof (Collar Only)
The collar is IP67 waterproof — but the remote is NOT.
What IP67 means: Submersible up to 1 meter for 30 minutes. Rain, mud, and brief swims are fine.
Important limitation: The remote must be kept away from water.
Compared to Delupet: Delupet has IPX8 (fully submersible, both collar and remote) — better for swimming dogs.
Dr. Jackson’s take: “IP67 is fine for rain, mud, and brief swims. For dogs who swim regularly — weekly trips to the lake — Delupet’s IPX8 is better. For most owners, IP67 is sufficient. Just keep the remote dry.”
Security Lock & Wide Fit Range
The Colofrog includes a security lock and fits a wide range of neck sizes.
Security Lock: Instant on/off switch — prevents accidental shocks when remote is in pocket or bag.
Neck size: 8-25 inches — fits everything from a small Frenchie to a giant Great Dane.
Dr. Jackson’s take: *”The 8-25 inch neck range is excellent — fits a wide variety of breeds. The security lock is standard on quality collars and prevents accidental stimulation. Always lock the remote when not actively training.”*
Fit and Comfort — Giant Breed Friendly
The Colofrog fits dogs 10-150 lbs with neck sizes 8-25 inches — the highest weight capacity in the 2-in-1 category.
What fits:
- Small breeds (10-20 lbs): Beagles, French Bulldogs, Corgis (minimum 10 lbs)
- Medium breeds (20-50 lbs): Border Collies, Australian Shepherds, Cavaliers
- Large breeds (50-90 lbs): Labradors, German Shepherds, Golden Retrievers, Boxers
- Giant breeds (90-150 lbs): Great Danes, Mastiffs, Saint Bernards, Rottweilers
What does NOT fit:
- Toy breeds under 10 lbs: Chihuahuas, Yorkies, Maltese — the collar starts at 10 lbs
Comfort features:
- Soft nylon strap
- Adjustable 8-25 inches
- Lightweight receiver
Dr. Jackson’s take: *”The 150 lb maximum is Colofrog’s standout feature. Giant breed owners often struggle to find collars that fit their dogs. Most 2-in-1 collars top out at 100-120 lbs. The Colofrog goes to 150 lbs. If you have a Great Dane or Mastiff over 120 lbs, this is one of your few options.”*

How to Use the Colofrog 2-in-1 Collar Safely
Follow these steps to ensure safe, effective training with both modes.
Step 1: Choose Your Mode
Bark Control Mode: Automatic bark detection — no remote needed. Use when you’re not actively training.
Dog Training Mode: Remote control only. Use for obedience, recall, and correcting specific behaviors.
All Mode: Both active simultaneously. Remote training plus automatic bark correction.
Step 2: Fit the Collar Properly
- Adjust strap to fit snugly (two-finger rule)
- Fits necks 8-25 inches
- Ensure contact points touch skin (trim fur if needed)
Step 3: For Training Mode — Find Lowest Effective Level
- Start at Shock level 1
- Increase slowly until your dog shows a subtle response (ear twitch, head turn)
- Small dogs (10-20 lbs): level 1-4
- Medium dogs (20-50 lbs): level 5-10
- Large/giant dogs (50-150 lbs): level 5-15
- If your dog yelps or cowers, the level is too high
Step 4: For Bark Control Mode — Set Sensitivity
- Start at level 3 (medium sensitivity)
- Adjust based on your dog’s barking volume
- Choose working state: Beep+Vibration (gentle) or Beep+Vibration+Shock (with static)
- Test by having someone else make noise while you observe
Step 5: Use Security Lock
- Engage on/off switch when not training
- Prevents accidental stimulation when remote is in pocket or bag
Dr. Jackson’s safety note: *”The 150 lb capacity is impressive, but a 10 lb dog and a 150 lb dog are vastly different. Start at level 1. Always. For giant breeds, you may need level 10-15. Work up slowly. If your dog yelps, you’ve gone too far — go back down.”*

FAQs About Colofrog Dog Collar
Is the Colofrog really 2-in-1? How does it work?
Yes — the Colofrog has three modes: Bark Control Mode (automatic bark detection — no remote needed), Dog Training Mode (remote control only), and All Mode (both active). One collar does the job of two separate devices. The key difference is that bark control mode works without the remote.
Will this collar fit my 150 lb Great Dane?
Yes — the Colofrog is rated for dogs up to 150 lbs, the highest capacity in this category. Most 2-in-1 collars top out at 100-120 lbs. If you have a giant breed over 120 lbs, this is one of your few options. Just ensure the neck size is within 8-25 inches.
How long does the battery last?
Remote: 50 days (best in class — charge every other month). Collar: 35 days (charge once a month). Charge time: 2 hours. This is excellent battery life — better than Aikeep and matches Delupet on the collar. The 50-day remote battery is the longest in this category.
Is the remote waterproof?
No — the collar is IP67 waterproof, but the remote must be kept away from water. This is consistent with Aikeep and Bousnic. Only the Delupet (IPX8) has fully waterproof collar and remote. Keep the Colofrog remote dry — use a dry bag near water.
How does Colofrog compare to Delupet?
Colofrog has higher weight capacity (150 lbs vs 100 lbs), longer remote battery (50 vs 45 days), and more reviews (2,652 vs 355 — proven track record). Delupet has longer range (4,500 ft vs 3,300 ft), IPX8 waterproof (vs IP67), and an LED light. Choose Colofrog for giant breeds and proven reliability; choose Delupet for premium specs.
Will this collar fit my small dog?
The collar fits dogs 10-150 lbs with neck sizes 8-25 inches. If your dog is under 10 lbs, this collar will not fit properly. For dogs under 10 lbs, consider the Bousnic (fits 5-120 lbs) instead. The Aikeep fits 8-120 lbs, so that’s another option for dogs 8-10 lbs.
What are the 2 working states in bark mode?
The bark collar has two working states: Beep + Vibration (gentle, no shock — start here) and Beep + Vibration + Safe Shock (includes static stimulation). You can choose based on your dog’s sensitivity. Most dogs respond to vibration alone. Only add shock if vibration doesn’t work.
Is the Colofrog good for first-time users?
Yes — the 2-in-1 design lets you start with bark control mode (automatic, no remote needed) and graduate to remote training as you learn. The 99 levels give you fine-tuning ability. The security lock prevents accidental shocks. The 4.4★ rating from 2,652 reviews suggests many first-time users are satisfied.
Verdict: Should You Buy the Colofrog 2-in-1 Collar?
Who the Colofrog is FOR:
- ✅ Owners of large and giant breeds (up to 150 lbs) — its standout feature
- ✅ Owners who want long remote battery life (50 days — best in class)
- ✅ Owners who want a well-established product (2,652 reviews, 4.4★)
- ✅ Owners who want 2-in-1 functionality at a reasonable price ($59.99)
- ✅ Owners who need 3,300 ft range (sufficient for most)
Who the Colofrog is NOT FOR:
- ❌ Owners with dogs under 10 lbs (won’t fit — choose Bousnic)
- ❌ Owners who need maximum range (4,500+ ft) — choose Delupet
- ❌ Owners who need IPX8 waterproofing for swimming dogs — choose Delupet
- ❌ Owners who want an LED light on the collar — Delupet has this
Final Verdict
*”The Colofrog 2-in-1 Dog Collar’s standout feature is its 150 lb weight capacity — the highest in the 2-in-1 category. Giant breed owners — Great Danes, Mastiffs, Saint Bernards — are often excluded from standard collars. The Colofrog is one of the few that fits them. The 50-day remote battery is also best in class — charge every other month. The 2-in-1 design (remote training + automatic bark control) matches the Aikeep and Delupet.
The 3,300 ft range, 99 shock levels, and IP67 waterproofing are all solid. The downsides? Dogs under 10 lbs won’t fit. The remote isn’t waterproof. And it lacks the LED light of the Delupet. But if you have a giant breed or want the longest remote battery, the Colofrog is an excellent choice. With 2,652 reviews and a 4.4-star rating, it’s also the most established 2-in-1 collar in this comparison. For giant breed owners, this is the best 2-in-1 option on the market.”* — Dr. Allona Jackson, DVM (12 years experience)
