Benefits of installing a dog flap
There are a load of benefits that justify the cost of dog flap installation. They include:
Convenience – You don’t have to worry about letting your dog in and out of the house. This is particularly useful if you work long hours.
Keeps your dog stimulated – Having a dog flap can combat boredom for many dogs. They’ll also get stimulation from the sights, sounds and smells of being outside.
Less door damage – Your dog won’t need you to let them out anymore so they’re much less likely to scratch or bite at the door.
Fewer doggy accidents indoors – A dog flap means your pup can go outside whenever they need to do their business. Hallelujah for clean floors and carpets.
Tips for installing a dog flap
When planning to install a dog flap, here are a few tips to remember:
The dog flap should be about 2 inches larger than the height and width of your dog to ensure they have easy access.
A standard dog flap with a spring mechanism is the most affordable type but will allow any pets or small animals to use it.
Advanced dog flaps use microchip technology to control the door so only your dog can enter or exit, but they are more expensive.
Speak to your local dog flap specialists for their professional advice and accurate quotes.
Shop around for fair and competitive dog flap installation costs.
Always hire a tradesperson with relevant experience and qualifications or accreditations.
