5yr old lab
£50/month insurance petplan
£11/month health plan (vacs, worming, flea, health checks)
£50 for 6 weeks of quality dog food
£16 week for 2 x 1hr dog walks
£5 week on treats
Then various costs like bedding, collars/leads, nail trimming, boarding, vet bills/excesses, shampoo, toys, waterproof coats/welllies/walking boots for winter walking. Crates, car restraints/guards (new estate car here too so 34kg of lab has enough room!), vet bed.
Also, if you go for a puppy add on damages during first 12-18 months - new carpets (edges chewed), redecoration (due to chewed skirting /wall one night), sofa (chewed/ripped open seat and ate foam), curtains, several dog beds, brand new football boots, shoes, books, all chewed.
Dh taking time off work (self employed) to take to/bring back from vet referrals, operations 80 miles away cost us a few hundred.
If done responsibly they are not cheap pets, you've got to enjoy walking in the rain/dark/cold and the smell of damp dog but worth every penny.
